The dually acylated NH2-terminal domain of gi1alpha is sufficient to target a green fluorescent protein reporter to caveolin-enriched plasma membrane domains. Palmitoylation of caveolin-1 is required for the recognition of dually acylated g-protein alpha subunits in vivo. (1/1802)

Here we investigate the molecular mechanisms that govern the targeting of G-protein alpha subunits to the plasma membrane. For this purpose, we used Gi1alpha as a model dually acylated G-protein. We fused full-length Gi1alpha or its extreme NH2-terminal domain (residues 1-32 or 1-122) to green fluorescent protein (GFP) and analyzed the subcellular localization of these fusion proteins. We show that the first 32 amino acids of Gi1alpha are sufficient to target GFP to caveolin-enriched domains of the plasma membrane in vivo, as demonstrated by co-fractionation and co-immunoprecipitation with caveolin-1. Interestingly, when dual acylation of this 32-amino acid domain was blocked by specific point mutations (G2A or C3S), the resulting GFP fusion proteins were localized to the cytoplasm and excluded from caveolin-rich regions. The myristoylated but nonpalmitoylated (C3S) chimera only partially partitioned into caveolin-containing fractions. However, both nonacylated GFP fusions (G2A and C3S) no longer co-immunoprecipitated with caveolin-1. Taken together, these results indicate that lipid modification of the NH2-terminal of Gi1alpha is essential for targeting to its correct destination and interaction with caveolin-1. Also, a caveolin-1 mutant lacking all three palmitoylation sites (C133S, C143S, and C156S) was unable to co-immunoprecipitate these dually acylated GFP-G-protein fusions. Thus, dual acylation of the NH2-terminal domain of Gi1alpha and palmitoylation of caveolin-1 are both required to stabilize and perhaps regulate this reciprocal interaction at the plasma membrane in vivo. Our results provide the first demonstration of a functional role for caveolin-1 palmitoylation in its interaction with signaling molecules.  (+info)

The Npc1 mutation causes an altered expression of caveolin-1, annexin II and protein kinases and phosphorylation of caveolin-1 and annexin II in murine livers. (2/1802)

We have previously demonstrated (1) an increased expression of caveolin-1 in murine heterozygous and homozygous Niemann-Pick type C (NPC) livers, and (2) an increased concentration of unesterified cholesterol in a detergent insoluble caveolae-enriched fraction from homozygous livers. To define further the relationship between caveolin-1 function and the cholesterol trafficking defect in NPC, we examined the expression and distribution of additional caveolar and signal transduction proteins. The expression of annexin II was significantly increased in homozygous liver homogenates and the Triton X-100 insoluble floating fraction (TIFF). Phosphoamino acid analysis of caveolin-1 and annexin II from the homozygous TIFF demonstrated an increase in serine and tyrosine phosphorylation, respectively. To determine the basis for increased phosphorylation of these proteins, the expression and distribution of several protein kinases was examined. The expression of PKCalpha, PKCzeta and pp60-src (protein kinases) were significantly increased in both heterozygous and homozygous liver homogenates, while PKCdelta was increased only in homozygous livers. Of the protein kinases analyzed, only CK IIalpha was significantly enriched in the heterozygous TIFF. Finally, the concentration of diacylglycerol in the homozygous TIFF was significantly increased and this elevation may modulate PKC distribution and function. These results provide additional evidence for involvement of a caveolin-1 containing cellular fraction in the pathophysiology of NPC and also suggest that the Npc1 gene product may directly or indirectly, regulate the expression and distribution of signaling molecules.  (+info)

Hypercholesterolemia decreases nitric oxide production by promoting the interaction of caveolin and endothelial nitric oxide synthase. (3/1802)

Hypercholesterolemia is a central pathogenic factor of endothelial dysfunction caused in part by an impairment of endothelial nitric oxide (NO) production through mechanisms that remain poorly characterized. The activity of the endothelial isoform of NO synthase (eNOS) was recently shown to be modulated by its reciprocal interactions with the stimulatory Ca2+-calmodulin complex and the inhibitory protein caveolin. We examined whether hypercholesterolemia may reduce NO production through alteration of this regulatory equilibrium. Bovine aortic endothelial cells were cultured in the presence of serum obtained from normocholesterolemic (NC) or hypercholesterolemic (HC) human volunteers. Exposure of endothelial cells to the HC serum upregulated caveolin abundance without any measurable effect on eNOS protein levels. This effect of HC serum was associated with an impairment of basal NO release paralleled by an increase in inhibitory caveolin-eNOS complex formation. Similar treatment with HC serum significantly attenuated the NO production stimulated by the calcium ionophore A23187. Accordingly, higher calmodulin levels were required to disrupt the enhanced caveolin-eNOS heterocomplex from HC serum-treated cells. Finally, cell exposure to the low-density lipoprotein (LDL) fraction alone dose-dependently reproduced the inhibition of basal and stimulated NO release, as well as the upregulation of caveolin expression and its heterocomplex formation with eNOS, which were unaffected by cotreatment with antioxidants. Together, our data establish a new mechanism for the cholesterol-induced impairment of NO production through the modulation of caveolin abundance in endothelial cells, a mechanism that may participate in the pathogenesis of endothelial dysfunction and the proatherogenic effects of hypercholesterolemia.  (+info)

Regulation of G protein-coupled receptor kinases by caveolin. (4/1802)

G protein-coupled receptor kinases (GRKs) have been principally characterized by their ability to phosphorylate and desensitize G protein-coupled receptors. However, recent studies suggest that GRKs may have more diverse protein/protein interactions in cells. Based on the identification of a consensus caveolin binding motif within the pleckstrin homology domain of GRK2, we tested the direct binding of purified full-length GRK2 to various glutathione S-transferase-caveolin-1 fusion proteins, and we discovered a specific interaction of GRK2 with the caveolin scaffolding domain. Interestingly, analysis of GRK1 and GRK5, which lack a pleckstrin homology domain, revealed in vitro binding properties similar to those of GRK2. Maltose-binding protein caveolin and glutathione S-transferase-GRK fusion proteins were used to map overlapping regions in the N termini of both GRK2 and GRK5 that appear to mediate conserved GRK/caveolin interactions. In vivo association of GRK2 and caveolin was suggested by co-fractionation of GRK2 with caveolin in A431 and NIH-3T3 cells and was further supported by co-immunoprecipitation of GRK2 and caveolin in COS-1 cells. Functional significance for the GRK/caveolin interaction was demonstrated by the potent inhibition of GRK-mediated phosphorylation of both receptor and peptide substrates by caveolin-1 and -3 scaffolding domain peptides. These data reveal a novel mode for the regulation of GRKs that is likely to play an important role in their cellular function.  (+info)

Analysis of the CAVEOLIN-1 gene at human chromosome 7q31.1 in primary tumours and tumour-derived cell lines. (5/1802)

We identified CAVEOLIN-1 as a candidate for a tumour suppressor gene mapping to human chromosome 7q31.1. A number of studies suggest that caveolin could function as a tumour suppressor. Expression of caveolin, and in turn the number of caveolae within a cell, are inversely correlated with the transforming ability of numerous oncoproteins, including H-ras, v-abl, and bcr-abl, and caveolin is a major transformation-dependent substrate of v-src. Heterologous expression of caveolin has been shown to abrogate anchorage-independent growth and induce apoptosis in transformed fibroblasts and also to suppress anchorage-independent growth in human mammary carcinoma cells. We have analysed the status and expression of the human CAVEOLIN-1 gene in primary tumours and tumour-derived cell lines. We found no evidence for mutation of CAVEOLIN-1 in human cancers. Additionally, we found that while the first two exons of CAVEOLIN-1 are associated with a CpG island, this is not methylated in either primary tumours or in tumour-derived cell lines in which Caveolin-1 expression is low or undetectable. The level of expression of Caveolin-1 does not correlate with loss of heterozygosity at the CAVEOLIN-1 locus in these same cell lines. Contrary to other published studies, we have shown that CAVEOLIN-1 is not expressed in normal breast ductal epithelial cells in vivo. CAVEOLIN-1 is however highly expressed in breast myoepithelial cells and its expression is retained in tumours derived from breast myoepithelium. Together our data refute a role for CAVEOLIN-1 as a breast tumour suppressor gene in vivo.  (+info)

A role for caveolin and the urokinase receptor in integrin-mediated adhesion and signaling. (6/1802)

The assembly of signaling molecules surrounding the integrin family of adhesion receptors remains poorly understood. Recently, the membrane protein caveolin was found in complexes with beta1 integrins. Caveolin binds cholesterol and several signaling molecules potentially linked to integrin function, e.g., Src family kinases, although caveolin has not been directly implicated in integrin-dependent adhesion. Here we report that depletion of caveolin by antisense methodology in kidney 293 cells disrupts the association of Src kinases with beta1 integrins resulting in loss of focal adhesion sites, ligand-induced focal adhesion kinase (FAK) phosphorylation, and adhesion. The nonintegrin urokinase receptor (uPAR) associates with and stabilizes beta1 integrin/caveolin complexes. Depletion of caveolin in uPAR-expressing 293 cells also disrupts uPAR/integrin complexes and uPAR-dependent adhesion. Further, beta1 integrin/caveolin complexes could be disassociated by uPAR-binding peptides in both uPAR-transfected 293 cells and human vascular smooth muscle cells. Disruption of complexes by peptides in intact smooth muscle cells blocks the association of Src family kinases with beta1 integrins and markedly impairs their migration on fibronectin. We conclude that ligand-induced signaling necessary for normal beta1 integrin function requires caveolin and is regulated by uPAR. Caveolin and uPAR may operate within adhesion sites to organize kinase-rich lipid domains in proximity to integrins, promoting efficient signal transduction.  (+info)

Visualization of caveolin-1, a caveolar marker protein, in living cells using green fluorescent protein (GFP) chimeras. The subcellular distribution of caveolin-1 is modulated by cell-cell contact. (7/1802)

Caveolin-1, a suspected tumor suppressor, is a principal protein component of caveolae in vivo. Recently, we have shown that NIH 3T3 cells harboring anti-sense caveolin-1 exhibit a loss of contact inhibition and anchorage-independent growth. These observations may be related to the ability of caveolin-1 expression to positively regulate contact inhibition. In order to understand the postulated role of caveolin-1 in contact inhibition, it will be necessary to follow the distribution of caveolins in living cells in response to a variety of stimuli, such as cell density. Here, we visualize the distribution of caveolin-1 in living normal NIH 3T3 cells by creating GFP-fusion proteins. In many respects, the behavior of these GFP-caveolin-1 fusion proteins is indistinguishable from endogenous caveolin-1. These GFP-caveolin-1 fusion proteins co-fractionated with endogenous caveolin-1 using an established protocol that separates caveolae-derived membranes from the bulk of cellular membranes and cytosolic proteins, and co-localized with endogenous caveolin-2 in vivo as seen by immunofluorescence microscopy. We show here that as NIH 3T3 cells become confluent, the distribution of GFP-caveolin-1 and endogenous caveolin-1 shifts to areas of cell-cell contact, coincident with contact inhibition. However, unlike endogenous caveolin-1, the levels of GFP-caveolin-1 expression are unaffected by changes in cell density, serum starvation, or growth factor stimulation. These results are consistent with the idea that the levels of endogenous caveolin-1 are modulated by either transcriptional or translational control, and that this modulation is separable from density-dependent regulation of the distribution of caveolin-1. These studies provide a new living-model system for elucidating the dynamic mechanisms underlying the density-dependent regulation of the distribution of caveolin-1 and how this relates to contact inhibition.  (+info)

Tyrosine-phosphorylated caveolin-1: immunolocalization and molecular characterization. (8/1802)

Caveolin-1 was discovered as a major substrate for v-Src, but the effect of its tyrosine phosphorylation has not been known. We generated a specific antibody (PY14) to caveolin-1 phosphorylated at tyrosine 14 and studied the significance of the modification. By Western blotting of lysates of v-Src-expressing cells, PY14 recognized not only a 22-kDa band (the position of nonphosphorylated caveolin-1) but bands at 23-24 and 25 kDa. Bands of slower mobility were diminished by dephosphorylation and were also observed for mutant caveolin-1 lacking tyrosine 14. By immunofluorescence microscopy, PY14 did not label normal cells but detected large dots in v-Src-expressing cells. Immunoelectron microscopy revealed that the dots corresponded to aggregated caveolae and/or vesicles of various sizes; besides, the label was observed in intramembrane particle-free areas in the plasma membrane, which appeared to have been formed by fusion of flattened caveolae. A positive reaction with PY14 was found in normal cells after vanadate or pervanadate treatment; it occurred mainly at 22 kDa by Western blotting and was not seen as large dots by immunofluorescence microscopy. Detergent solubility, oligomerization, and association with caveolin-2 were observed similarly for caveolin-1 in normal and v-Src-expressing cells. The results indicate that phosphorylation of caveolin-1 in v-Src-expressing cells occurs at multiple residues and induces flattening, aggregation, and fusion of caveolae and/or caveolae-derived vesicles.  (+info)

Phospholipase D2 (PLD2) has been found localized in low-density caveolin-rich membrane microdomains. Our previous study suggested that PLD2 and aquaporin 3 (AQP3) interact in these domains to inhibit keratinocyte proliferation and promote differentiation by cooperating to produce phosphatidylglycerol. To examine the effect of membrane microdomain localization on the PLD2/AQP3 signaling module and keratinocyte proliferation and differentiation, we treated mouse keratinocytes with 3 µM cell-permeable caveolin-1 scaffolding domain peptide or a negative control peptide and stimulated cell differentiation using a moderately elevated extracellular calcium concentration (125 uM) to maximally promote differentiation and phosphatidylglycerol production. Cell proliferation, differentiation, total PLD activity, phosphatidylglycerol levels, and AQP3 activity were monitored. The caveolin-1 scaffolding domain peptide itself had no effect on phosphatidylglycerol levels or keratinocyte proliferation or ...

Brefeldin A treatment induced further accumulation of caveolin-2 along with caveolin-1 in LD. Analysis of mouse caveolin-2 deletion mutants revealed that the central hydrophobic domain (residues 87-119) and the NH2-terminal (residues 70-86) and COOH-terminal (residues 120-150) hydrophilic domains are all necessary for the localization in LD. The NH2- and COOH-terminal domains appeared to be related to membrane binding and exit from ER, respectively, implying that caveolin-2 is ...

Caveolae are plasma membrane microdomains that localise receptors and signalling intermediates within an environment where they can efficiently trigger downstream events. While present in most cells types, they are particularly abundant in vascular smooth muscle cells and endothelial cells (ECs), where they regulate low density lipoprotein trans-cytosis, NO production and inflammation. Cavin-1 is a protein required for caveolae maturation, such that its deletion results in no detectable caveolae and the down-regulation of caveolin scaffolding proteins. However, the cellular processes regulating cavin-1 function are poorly understood. Proteomic screening and biochemical experiments have identified cavin-1 as a novel interacting protein of the cytokine-inducible E3 ubiquitin ligase component suppressor of cytokine signalling-3 (SOCS3), a key inhibitor of IL-6-mediated pro-inflammatory signalling in ECs. We hypothesise d that the SOCS3/cavin-1 interaction may be important in controlling caveola ...
Several exogenous and endogenous cargo proteins are internalized independently of clathrin, including the bacterial Shiga toxin. The mechanisms underlying early steps of clathrin-independent uptake remain largely unknown. In this study, we have designed a protocol to obtain gradient fractions containing Shiga toxin internalization intermediates. Using stable isotope labeling with amino acids in cell culture (SILAC) and quantitative mass spectrometry, Rab12 was found in association with these very early uptake carriers. The localization of the GTPase on Shiga toxin-induced plasma membrane invaginations was shown by fluorescence microscopy in cells transfected with GFP-Rab12. Furthermore, using a quantitative biochemical assay, it was found that the amount of receptor-binding B-subunit of Shiga toxin reaching the trans-Golgi/TGN membranes was decreased in Rab12-depleted cells, and that cells were partially protected against intoxication by Shiga-like toxin 1 under these conditions. These findings ...
The complex interplay of the tumour microenvironment (TME) and its role in disease progression and response to therapy is poorly understood. The majority of studies to date focus on individual components or molecules within the TME and so lack the power correlative analysis. Here we have performed a multi-parameter analysis of the TME in 62 resectable non-small cell lung cancer (NSCLC) specimens detailing number and location of immune infiltrate, assessing markers of cancer-associated fibroblasts, caveolin-1 and tenascin-C, and correlating with clinicopathological details, as well as markers of disease progression such as epithelial-to-mesenchymal transition (EMT). The influence of individual parameters on overall survival was determined in univariate and multivariate analysis and the combination of risk factors and interplay between components analysed. Low numbers of CD8 T cells, low stromal levels of caveolin-1 or high levels of tenascin-C were significant prognostic markers of decreased ...
TY - JOUR. T1 - Circulating cardiovascular disease risk factors and signaling in endothelial cell caveolae. AU - Mineo, Chieko. AU - Shaul, Philip W.. PY - 2006/4/1. Y1 - 2006/4/1. N2 - Caveolae are a subset of lipid rafts that are prevalent on the plasma membrane of endothelial cells. They compartmentalize signal transduction molecules which regulate multiple endothelial functions including the production of nitric oxide (NO) by the caveolae resident enzyme endothelial NO synthase (eNOS). Recent studies have demonstrated that circulating factors known to modify cardiovascular disease risk regulate signaling in endothelial cell caveolae. In particular, high density lipoprotein (HDL) maintains the lipid environment in caveolae, thereby promoting the retention and function of eNOS in the domain, and it also causes direct activation of eNOS via scavenger receptor type BI (SR-BI)-induced kinase signaling. Estrogen binding to estrogen receptors (ER) in caveolae also activates eNOS, and this occurs ...

However, the regulatory mechanism of caveolin-1 phosphorylation remains unclear. Here we identify a previously unexpected role for AMPKin inhibition of caveolin-1 phosphorylation under oxidative stress. A pharmacological activator of AMPK, ...

Caveolin-1 (Cav-1), a major structural component of cell membrane caveolae, is involved in a variety of intracellular signaling pathways as well as transmembrane transport. Cav-1, as a scaffolding protein, modulates signal transduction associated with cell cycle progression, cellular senescence, cell proliferation and death, lipid homeostasis, etc. Cav-1 is also thought to regulate the expression or activity of oncoproteins, such as Src family kinases, H-Ras, protein kinase C, epidermal growth factor, extracellular signal-regulated kinase, and endothelial nitric oxide synthase. Because of its frequent overexpression or mutation in various tumor tissues and cancer cell lines, Cav-1 has been speculated to play a role as an oncoprotein in cancer development and progression. In contrast, Cav-1 may also function as a tumor suppressor, depending on the type of cancer cells and/or surrounding -stromal cells in the tumor microenvironment as well as the stage of tumors ...

Proteins and other substances can cross the endothelial layer that lines a blood vessel via two routes. Caveolin-1 is essential for both, Siddiqui et al. show.. Researchers already knew that caveolin-1 was necessary for transcellular protein trafficking, in which macromolecules such as albumin enter an endothelial cell from the bloodstream and exit on the tissue side. Caveolae swallow these molecular travelers and bundle them into vesicles that wend through the cell. In an alternative pathway, known as the paracellular route, molecules slip between the cells of the endothelial layer, passing through the adherens junctions that fasten adjacent cells together. Previous work showed that adherens junctions become permeable in mice lacking caveolin-1, suggesting that the protein helps seal the junctions.. Siddiqui et al. dissected the molecular chain of events that connects caveolin-1 to adherens junction integrity. Loss of caveolin-1 activated the enzyme eNOS, which spawns nitric oxide (NO) that ...
Caveolae are specialised forms of lipid rafts in the plasma membrane of most cells. They form dynamic assemblies of sphingolipids and cholesterol containing scaffolding domains with different affinities for proteins resulting in a variety of functions [1]. The constitutive Cav-1 protein is distributed ubiquitously, while Cav-2 is usually associated with Cav-1 [3, 28]. Although Cav-3 is thought to be muscle specific and is expressed in striated muscles [3, 28, 29], we and others have found that Cav-3 is not expressed within human ASM [6, 30]. Recent studies have established that ASM caveolae contain a number of proteins important to [Ca2+]i regulation (e.g. agonist receptors, Ca2+ influx channels, and force regulatory proteins such as RhoA). In canine ASM, it has been established that caveolar-enriched membrane fractions express Cav-1, L-type Ca2+ channels and plasma membrane Ca2+ ATPase, but not SR proteins such as IP3R or RyR channels [31].. In ASM of different species, in addition to Ca2+ ...
Caveolae are small, cholesterol-rich, hydrophobic membrane domains, characterized by the presence of the protein caveolin and involved in several cellular processes, including clathrin-independent endocytosis, the regulation and transport of cellular cholesterol, and signal transduction. Recently, c …
Lipids are the energy source used during liver regeneration. The research group, led by Dr. Albert Pol and with members from IDIBAPS, Universitat de Barcelona and Queensland University, unveils the essential role of the protein caveolin-1 in a fundamental process for liver cure after injury or transplant. Results also evidence the existence of cellular mechanisms by which excessive accumulation of lipids in the liver is a risk factor for the apparition of hepatic tumours.
Caveolin-3 (Cav-3) is a protein that has been implicated in t-tubule formation and function in cardiac ventricular myocytes. In cardiac hypertrophy and failure, Cav-3 expression decreases, t-tubule structure is disrupted and excitation-contraction coupling (ECC) is impaired. However, the extent to which the decrease in Cav-3 expression underlies these changes is unclear. We therefore investigated the structure and function of myocytes isolated from the hearts of Cav-3 KO mice. These mice showed cardiac dilatation and decreased ejection fraction in vivo, compared to WT controls. Isolated KO myocytes showed cellular hypertrophy and altered t-tubule structure, and decreased L-type Ca channel (LTCC) current (ICa) density. This decrease in density occurred predominantly in the t-tubules, with no change in total ICa, and was therefore a consequence of the increase in membrane area. Cav-3 KO had no effect on LTCC expression, and C3SD peptide, which mimics the scaffolding domain of Cav-3, had no effect ...
Caveolae, the sphingomy-cholesterol enriched microdomains, form a stable lipid matrix that act as an ordered support for receptor-mediated signaling events. It has been proposed that caveola composition changes in response to adverse extracellular conditions [35,36]. Consistent with this hypothesis, we found in the current study that HG treatment led to a decrease in the number of caveolae on the surface of LECs. We also found reduced levels of caveolin-1 mRNA and protein in HG-treated LECs, indicating that caveolin-1 expression was down-regulated at the transcription level. Although it has been proposed that caveolin-1 functions as a message center that compartmentalizes anti- and pro-apoptotic signaling molecules on the cell surface to regulate apoptosis [17], its role in regulating apoptosis remains controversial. In the current study, we found the levels of caveolin-1 reduced and apoptosis rate increased in HG-treated LECs, indicating that caveolin-1 may inhibit apoptosis. However, ...

The primary function of adipose tissue is to store energy in the form of triacylglycerol, which is hydrolyzed to fatty acids to supply other tissues with energy. While insulin promotes the storage of triacylglycerol, catecholamines stimulate its hydrolysis. The development of type II diabetes is strongly associated with obesity, indicating a role of triacylglycerol metabolism in the pathogenesis of diabetes. Caveolae are plasma membrane invaginations found in most cells but are highly abundant in adipocytes. Insulin receptors are localized in caveolae and their function depends on intact caveolae structures. In the present thesis work, mass spectrometry-based methodology allowed identification of a number of new proteins and their posttranslational modifications in caveolae of human adipocytes. Variable N-terminal acetylation and phosphorylation of caveolin-1α and caveolin-1β were identified, which might regulate the function of caveolae. The transcription regulator protein PTRF was identified ...
TY - CHAP. T1 - Role of caveolae in the airway. AU - Pabelick, Christina M. AU - Singh, Brij B.. AU - Prakash, Y.s.. PY - 2013/11/1. Y1 - 2013/11/1. N2 - Caveolae are flask-shaped invaginations of the plasma membrane that are rich in lipids and serve as microdomains to facilitate interactions between proteins at the membrane as well as intracellular components, thus modulating signal transduction, protein and lipid transport, and other processes. Constituent caveolar proteins such as caveolins and cavins also have scaffolding domains that anchor and regulate protein function. There is now evidence that caveolae and their constituent proteins are present in airway smooth muscle in a variety of species. Caveolae in airway cells contain or interact with molecules such as receptors, ion channels, and regulatory proteins that are key to the roles of airway epithelium and smooth muscle in regulating airway structure and function. Furthermore, caveolar protein expression and regulation appear to be ...
Recently, we reported that the activities of large conductance Ca2+-activated K+(BK) channels are inhibited by caveolae microdomain targeting in vascular endothelial cells. The molecular mechanism of this negative regulation of BK channels by caveolae is unknown. In this study, we tested the hypotheses that BK channels are inhibited by physical interaction with the scaffolding domain of caveolin-1, which alters the properties of the channel. Using HEK293 cells stably expressing hSlo (which encodes human BK channels) with and without transient transfection with caveolin-1, We found that hSlo channels were enriched in the low buoyant density fraction when co-expressed with caveolin-1 and the channels were co-immunoprecipitated by anti-caveolin-1 antibodies. Co-expression of caveolin-1 resulted in inhibition of whole-cell hSlo current densities from 77.0±18.0 pA/pF in control (HP=−60 mV, TP=+80 mV, 1 μM free Ca2+, n=10) to 12.0±3.9 pA/pF (n=8, p,0.01 vs. control). In contrast, co-expression of ...
Caveolae are specialized flask-shaped lipid rafts enriched in cholesterol, sphingolipids, and structural marker proteins termed caveolins. Caveolins are highly conserved hairpin loop-shaped, oligomeric proteins of 22-24 kDa. Besides the plasma cell membrane, caveolins are also present in mitochondri …
Caveolins act as scaffold proteins in multiprotein complexes and have been implicated in signaling by G protein-coupled receptors. Studies using knock-out mice suggest that beta(3)-adrenoceptor (beta(3)-AR) signaling is dependent on caveolin-1; however, it is not known whether caveolin-1 is associated with the beta(3)-AR or solely with downstream signaling proteins. We have addressed this question by examining the impact of membrane rafts and caveolin-1 on the differential signaling of mouse beta(3a)- and beta(3b)-AR isoforms that diverge at the distal C terminus. Only the beta(3b)-AR promotes pertussis toxin (PTX)-sensitive cAMP accumulation. When cells expressing the beta(3a)-AR were treated with filipin III to disrupt membrane rafts or transfected with caveolin-1 siRNA, the cyclic AMP response to the beta(3)-AR agonist CL316243 became PTX-sensitive, suggesting G alpha(i/o) coupling. The beta(3a)-AR C terminus, S (P-384) under bar PLNR (P-389) under bar DG (Y-392) under bar EGARP (P-398) under ...
Abstract: Low molecular weight protein tyrosine phosphatases (LMW-PTPs) are small enzymes that are ubiquitous in many organisms. They are important in biological processes such as cell proliferation, adhesion, migration, and invasiveness. LMW-PTP is expressed in mammalian cells as two isoforms (IF1 and IF2) originating through alternative splicing. We have previously shown that IF2 targets lipid rafts called caveolae and interacts with caveolin-1, their major structural protein. Caveolae are cholesterol- and sphingolipid-rich membrane microdomains that have been implicated in a variety of cellular functions, including signal transduction events. Caveolin-1 contains a scaffolding region that contributes to the binding of the protein to the plasma membrane and mediates protein omo- and etero-oligomerization. Interaction of many signaling molecules with the scaffolding domain sequesters them into caveolae and inhibits or suppresses their activities. Caveolin-interacting proteins usually have a ...
This is the first report that two different DIG fractions can be isolated from myelin by TX-100 extraction with sodium phosphate buffer lacking EDTA/EGTA, at room temperature. Both of these fractions have characteristics of GSL/cholesterol-enriched membrane domains based on their TX-100 insolubility, high ratios of cholesterol and GalC to phospholipid, enrichment in the GPI-linked protein NCAM120, and buoyancy on a sucrose density gradient. However, B2 also contained the cytoskeletal proteins actin and tubulin, and the raft markers flotillin-1, caveolin and GM1, and thus may consist of caveolae or other types of GSL/cholesterol-enriched membrane domain associated with cytoskeletal proteins. It does not contain non-membrane-associated cytoskeleton, which would sediment faster to a much higher density.. This finding of a caveolin-containing type of membrane domain associated with cytoskeletal proteins in myelin is also novel. Both caveolae and non-caveolar membrane domains have been found to ...
Caveolae. Caveolae were described in the fifties of the last century by P. Palade after observing animal tissues at transmission electron microscopy. They are small invaginations (45-80 nm) of the plasma membrane that can be observed in most of the eukaryotic cells. It was suggested that most of the caveolae become vesicles (but see below). Caveolae are abundant in endothelial cells, muscle cells and adipocytes. The membrane of the caveolae contains caveolin, as well as other integral proteins linked to glycosylphosphatidylinositol, many sphingolipids (sphingomyelin and glycosphingolipids), and is enriched in cholesterol. The presence of caveolin in a cell is enought to form caveolae. There are around 100 to 200 caveolin molecules in one caveola and there are different types of caveolin in one caveola. Caveolin 1 is expressed in smooth muscle cells and in most of the non muscle cells, and it is necessary for caveolae formation in these cells. Caveolin 2, which can be expressed in the same cells ...
This gene encodes a protein that enables the dissociation of paused ternary polymerase I transcription complexes from the 3 end of pre-rRNA transcripts. This protein regulates rRNA transcription by promoting the dissociation of transcription complexes and the reinitiation of polymerase I on nascent rRNA transcripts. This protein also localizes to caveolae at the plasma membrane and is thought to play a critical role in the formation of caveolae and the stabilization of caveolins. This protein translocates from caveolae to the cytoplasm after insulin stimulation. Caveolae contain truncated forms of this protein and may be the site of phosphorylation-dependent proteolysis. This protein is also thought to modify lipid metabolism and insulin-regulated gene expression. Mutations in this gene result in a disorder characterized by generalized lipodystrophy and muscular dystrophy. [provided by RefSeq, Nov 2009 ...
Caveolae are specialized domains present in the plasma membrane (PM) of most mammalian cell types. They function in signalling, membrane regulation, and endocytosis. We found that the Eps-15 homology domain-containing protein 2 (EHD2, an ATPase) associated with the static population of PM caveolae. Recruitment to the PM involved ATP binding, interaction with anionic lipids, and oligomerization into large complexes (60-75S) via interaction of the EH domains with intrinsic NPF/KPF motifs. Hydrolysis of ATP was essential for binding of EHD2 complexes to caveolae. EHD2 was found to undergo dynamic exchange at caveolae, a process that depended on a functional ATPase cycle. Depletion of EHD2 by siRNA or expression of a dominant-negative mutant dramatically increased the fraction of mobile caveolar vesicles coming from the PM. Overexpression of EHD2, in turn, caused confinement of cholera toxin B in caveolae. The confining role of EHD2 relied on its capacity to link caveolae to actin filaments. Thus, ...

Directional cell migration is crucially dependent on the spatiotemporal control of intracellular signalling events. These events regulate polarized actin dynamics, resulting in protrusion at the front of the cell and contraction at the rear. The actin cytoskeleton is regulated through signalling by Rho-like GTPases, such as RhoA, which stimulates myosin-based contractility, and CDC42 and Rac1, which promote actin polymerization and protrusion. Here, we show that Rac1 binds the adapter protein caveolin-1 (Cav1) and that Rac1 activity promotes Cav1 accumulation at Rac1-positive peripheral adhesions. Using Cav1-deficient mouse fibroblasts and depletion of Cav1 expression in human epithelial and endothelial cells mediated by small interfering RNA and short hairpin RNA, we show that loss of Cav1 induces an increase in Rac1 protein and its activated, GTP-bound form. Cav1 controls Rac1 protein levels by regulating ubiquitylation and degradation of activated Rac1 in an adhesion-dependent fashion. ...

Objectives Reduced caveolin-1 levels in lung fibroblasts from patients with scleroderma and the lungs of bleomycin-treated mice promote collagen overexpression and lung fibrosis. This study was undertaken to determine whether caveolin-1 is deficient in leucocytes from bleomycin-treated mice and patients with scleroderma and to examine the consequences of this deficiency and its reversal.. Methods Mice or cells received the caveolin-1 scaffolding domain (CSD) peptide to reverse the pathological effects of reduced caveolin-1 expression. In bleomycin-treated mice, the levels of caveolin-1 in leucocytes and the effect of CSD peptide on leucocyte accumulation in lung tissue were examined. To validate the results in human disease and to identify caveolin-1-regulated molecular mechanisms, monocytes and neutrophils were isolated from patients with scleroderma and control subjects and caveolin-1, extracellular signal-regulated protein kinase (ERK), c-Jun N-terminal kinase (JNK), p38, CXC chemokine ...
Background: Muscle-restricted coiled-coil protein (MURC)/cavin-4 is a novel member of the cavin family that regulates caveolae function. Caveolae formation and function are also regulated by caveolin-3 in cardiomyocytes (CMs). Overexpression of caveolin-3 induces cardiac protection, and loss of caveolin-3 causes progressive cardiomyopathy. Mutations in MURC have been identified in patients with dilated cardiomyopathy. However, the role of MURC as a caveolar component protein remains unknown.. Methods and Results: To assess the role of MURC in the development of heart failure, MURC-knockout (KO) and wild-type (WT) mice were subjected to pressure overload by transverse aortic constriction (TAC). After TAC, WT mice developed overt heart failure and eccentric cardiac hypertrophy, whereas MURC-KO mice showed preserved cardiac function accompanied by attenuated cardiac hypertrophy. We then focused on β-adrenergic receptor (AR) signaling, because MURC was colocalized and associated with β1-AR. ...

Therefore, agents that preserve or restore vascular integrity have important therapeutic implications. In this study, we explored the regulation of hepatocyte growth factor (HGF)-mediated enhancement of EC barrier function via CD44 isoforms. We observed that HGF promoted c-Met association with CD44v10 and recruitment of c-Met into caveolin-enriched microdomains (CEM) containing CD44s (standard form). Treatment of EC with ...
Caveolae are specialized membrane domains that function in endocytosis and contain relatively high concentrations of signaling molecules. Isshiki et al. now present evidence that caveolae serve as preferential sites of Ca2+ influx across the plasma membrane when intracellular stores of Ca2+ are depleted. The authors fused the calcium sensor yellow chameleon 3.1 to the COOH-terminal end of caveolin-1 to target the sensor to caveolae. Then, they compared Ca2+ signals at the caveolae to those from unmodified yellow chameleon in the cytoplasm or from another fusion protein that targeted the sensor to the plasma membrane. When Ca2+ was depleted from the endoplasmic reticulum of fetal bovine endothelial cells by exposure of the cells to adenosine triphosphate (ATP) and thapsigargin, Ca2+ entry into the cells occurred preferentially at caveolae, apparently through store-operated channels of the TRP (transient receptor potential) family. The authors propose that caveolae may function as preassembled, ...
article{364f9c3e-a101-48eb-bf5b-ea6e0c163acd, abstract = {,p,Cavins belong to a family of proteins that contribute to the formation of caveolae, which are membrane organelles with functional roles in muscle and fat. Here, we investigate the effect of cavin-3 ablation on vascular and urinary bladder structure and function. Arteries and urinary bladders from mice lacking cavin-3 (knockout: KO) and from controls (wild type: WT) were examined. Our studies revealed that the loss of cavin-3 resulted in ∼40% reduction of the caveolae protein cavin-1 in vascular and bladder smooth muscle. Electron microscopy demonstrated that the loss of cavin-3 was accompanied by a reduction of caveolae abundance by 40-45% in smooth muscle, whereas the density of caveolae in endothelial cells was unchanged. Vascular contraction in response to an α,sub,1,/sub,-adrenergic agonist was normal but nitric-oxide-dependent relaxation was enhanced, in parallel with an increased relaxation on direct activation of soluble ...
In biology, caveolae (Latin for little caves; singular, caveola), which are a special type of lipid raft, are small (50-100 nanometer) invaginations of the plasma membrane in many vertebrate cell types, especially in endothelial cells, adipocytes and embryonic notochord cells. They were originally discovered by E. Yamada in 1955. These flask-shaped structures are rich in proteins as well as lipids such as cholesterol and sphingolipids and have several functions in signal transduction. They are also believed to play a role in mechanoprotection, mechanosensation, endocytosis, oncogenesis, and the uptake of pathogenic bacteria and certain viruses. Formation and maintenance of caveolae was initially thought to be primarily due to caveolin, a 21 kD protein. There are three homologous genes of caveolin expressed in mammalian cells: Cav1, Cav2 and Cav3. These proteins have a common topology: cytoplasmic N-terminus with scaffolding domain, long hairpin transmembrane domain and cytoplasmic C-terminus. ...
The plasma membrane is not uniform, but can be divided into different microdomains. Whereas some microdomains, such as clathrin-coated pits, are morphologically identifiable, others can be identified only upon colocalization with domain-specific marker molecules. Caveolae are microdomains originally identified morphologically as small noncoated invaginations of the plasma membrane. The formation of caveolae depends on expression of caveolin and, since the plasma membrane contains different noncoated invaginations, caveolae can be identified only by labeling for caveolin. Some confusion exists with respect to the relationship between caveolae and lipid rafts [see raft nomenclature ( Simons and Toomre, 2000)]. This is partly due to difficulties in isolating pure caveolae and to the various methods used for this purpose. Initially, subcellular fractionation upon Triton X-100 extraction at 4°C was used. Such fractionation allows the isolation of detergent-resistant membranes [DRMs; also called DIGs ...

The molecular composition of plasma membranes is constantly remodeled by endocytosis and exocytosis. Eisosomes are large cytoplasmic protein assemblies that localize to specialized domains on the yeast plasma membrane. They are of uniform size and immobile, and their disruption leads to large aberrant plasma membrane invaginations and endocytic defects. It is unknown how eisosomes are formed or inherited and what governs their size, distribution, and location. Here we show that eisosomes are formed de novo in the bud of dividing cells. They colonize newly formed membrane at a fixed density in a polarized wave proceeding from the bud neck to the bud tip and become anchored at the site of their formation. Pil1, one of the two main eisosome subunits, emerges as the central regulator of eisosome biogenesis that determines both size and location of eisosomes. Lowering Pil1 expression leads to normal-sized eisosomes at a reduced density, suggesting that eisosomes must be of a minimal size. Conversely, ...

Introduction. Caveolin-1(Cav-1) is a multifunctional scaffolding protein essential structural constituent of caveolae, regulating multiple processes in cancer.. A growing body of evidence links elevated expression of Cav-1 to an aggressive phenotype of cancer cells and to a poor prognosis in several tumors. The molecular mechanisms underlying the pro-survival and tumor-promoting functions of Cav-1 and the down-stream mediators of Cav-1 functional role in metastatic cancer have jet to be fully identified. The aim of the present work was to prosecute the investigation on such molecular pathways in solid tumors, based on our recent data obtained in cell lines from SCLC (SCLC-R1) and NSCLC (RAL) and from glioblastoma (A-172) where we demonstrated an oncopromoter activity of Cav-1 through the activation of STAT3 signaling pathway. Here we present the data obtained in a cell line from osteosarcoma (143B), where Cav-1 was highly expressed.. Methods. Cav-1 was knocked-down by siRNA using the ...
