Gamma-Actinin, a new regulatory protein from rabbit skeletal muscle. I. Purification and characterization. (1/917)

A new regulatory protein which we have designated as gamma-actinin has been isolated from native thin filaments of rabbit skeletal muscle. Depolymerized native thin filaments were fractionated by salting out with ammonium sulfate, and the precipitates obtained at 40--60% ammonium sulfate saturation were further subjected to DEAE-Sephadex and Sephadex G-200 column chromatography. The purified gamma-actinin was shown to have a chain weight of 35,000 daltons and had a strong inhibitory action on the polymerization of G-actin. The results of amino acid analysis indicated a unique amino acid composition of gamma-actinin as compared with other structural proteins of muscle. Non-polar and neutral amino acid residues were abundant. One cysteine residue was contained per one molecule of gamma-actinin and played a critical role in the maintenance of the inhibitory activity. Pelleting of gamma-actinin with F-actin showed that gamma-actinin binds to F-action.  (+info)

Polypyrimidine tract binding protein functions as a repressor to regulate alternative splicing of alpha-actinin mutally exclusive exons. (2/917)

The smooth muscle (SM) and nonmuscle (NM) isoforms of alpha-actinin are produced by mutually exclusive splicing of an upstream NM exon and a downstream SM-specific exon. A rat alpha-actinin genomic clone encompassing the mutually exclusive exons was isolated and sequenced. The SM exon was found to utilize two branch points located 382 and 386 nucleotides (nt) upstream of the 3' splice site, while the NM exon used a single branch point 191 nt upstream. Mutually exclusive splicing arises from the proximity of the SM branch points to the NM 5' splice site, and this steric repression could be relieved in part by the insertion of spacer elements. In addition, the SM exon is repressed in non-SM cells and extracts. In vitro splicing of spacer-containing transcripts could be activated by (i) truncation of the transcript between the SM polypyrimidine tract and exon, (ii) addition of competitor RNAs containing the 3' end of the actinin intron or regulatory sequences from alpha-tropomyosin (TM), and (iii) depletion of the splicing extract by using biotinylated alpha-TM RNAs. A number of lines of evidence point to polypyrimidine tract binding protein (PTB) as the trans-acting factor responsible for repression. PTB was the only nuclear protein observed to cross-link to the actinin RNA, and the ability of various competitor RNAs to activate splicing correlated with their ability to bind PTB. Furthermore, repression of alpha-actinin splicing in the nuclear extracts depleted of PTB by using biotinylated RNA could be specifically restored by the addition of recombinant PTB. Thus, alpha-actinin mutually exclusive splicing is enforced by the unusual location of the SM branch point, while constitutive repression of the SM exon is conferred by regulatory elements between the branch point and 3' splice site and by PTB.  (+info)

Tropomodulin assembles early in myofibrillogenesis in chick skeletal muscle: evidence that thin filaments rearrange to form striated myofibrils. (3/917)

Actin filament lengths in muscle and nonmuscle cells are believed to depend on the regulated activity of capping proteins at both the fast growing (barbed) and slow growing (pointed) filament ends. In striated muscle, the pointed end capping protein, tropomodulin, has been shown to maintain the lengths of thin filaments in mature myofibrils. To determine whether tropomodulin might also be involved in thin filament assembly, we investigated the assembly of tropomodulin into myofibrils during differentiation of primary cultures of chick skeletal muscle cells. Our results show that tropomodulin is expressed early in differentiation and is associated with the earliest premyofibrils which contain overlapping and misaligned actin filaments. In addition, tropomodulin can be found in actin filament bundles at the distal tips of growing myotubes, where sarcomeric alpha-actinin is not always detected, suggesting that tropomodulin caps actin filament pointed ends even before the filaments are cross-linked into Z bodies by alpha-actinin. Tropomodulin staining exhibits an irregular punctate pattern along the length of premyofibrils that demonstrate a smooth phalloidin staining pattern for F-actin. Strikingly, the tropomodulin dots often appear to be located between the closely spaced, dot-like Z bodies that are stained for (&agr;)-actinin. Thus, in the earliest premyofibrils, the pointed ends of the thin filaments are clustered and partially aligned with respect to the Z bodies (the location of the barbed filament ends). At later stages of differentiation, the tropomodulin dots become aligned into regular periodic striations concurrently with the appearance of striated phalloidin staining for F-actin and alignment of Z bodies into Z lines. Tropomodulin, together with the barbed end capping protein, CapZ, may function from the earliest stages of myofibrillogenesis to restrict the lengths of newly assembled thin filaments by capping their ends; thus, transitions from nonstriated to striated myofibrils in skeletal muscle are likely due principally to filament rearrangements rather than to filament polymerization or depolymerization. Rearrangements of actin filaments capped at their pointed and barbed ends may be a general mechanism by which cells restructure their actin cytoskeletal networks during cell growth and differentiation.  (+info)

An alpha-actinin binding site of zyxin is essential for subcellular zyxin localization and alpha-actinin recruitment. (4/917)

The LIM domain protein zyxin is a component of adherens type junctions, stress fibers, and highly dynamic membrane areas and appears to be involved in microfilament organization. Chicken zyxin and its human counterpart display less than 60% sequence identity, raising concern about their functional identity. Here, we demonstrate that human zyxin, like the avian protein, specifically interacts with alpha-actinin. Furthermore, we map the interaction site to a motif of approximately 22 amino acids, present in the N-terminal domain of human zyxin. This motif is both necessary and sufficient for alpha-actinin binding, whereas a downstream region, which is related in sequence, appears to be dispensable. A synthetic peptide comprising human zyxin residues 21-42 specifically binds to alpha-actinin in solid phase binding assays. In contrast to full-length zyxin, constructs lacking this motif do not interact with alpha-actinin in blot overlays and fail to recruit alpha-actinin in living cells. When zyxin lacking the alpha-actinin binding site is expressed as a fusion protein with green fluorescent protein, association of the recombinant protein with stress fibers is abolished, and targeting to focal adhesions is grossly impaired. Our results suggest a crucial role for the alpha-actinin-zyxin interaction in subcellular zyxin localization and microfilament organization.  (+info)

Viscoelastic properties of f-actin, microtubules, f-actin/alpha-actinin, and f-actin/hexokinase determined in microliter volumes with a novel nondestructive method. (5/917)

A nondestructive method to determine viscoelastic properties of gels and fluids involves an oscillating glass fiber serving as a sensor for the viscosity of the surrounding fluid. Extremely small displacements (typically 1-100 nm) are caused by the glass rod oscillating at its resonance frequency. These displacements are analyzed using a phase-sensitive acoustic microscope. Alterations of the elastic modulus of a fluid or gel change the propagation speed of a longitudinal acoustic wave. The system allows to study quantities as small as 10 microliters with temporal resolution >1 Hz. For 2-100 microM f-actin gels a final viscosity of 1.3-9.4 mPa s and a final elastic modulus of 2.229-2.254 GPa (corresponding to 1493-1501 m/s sound velocity) have been determined. For 10- to 100-microM microtubule gels (native, without stabilization by taxol), a final viscosity of 1.5-124 mPa s and a final elastic modulus of 2.288-2. 547 GPa (approximately 1513-1596 m/s) have been determined. During polymerization the sound velocity in low-concentration actin solutions increased up to +1.3 m/s (approximately 1.69 kPa) and decreased up to -7 m/s (approximately 49 kPa) at high actin concentrations. On polymerization of tubulin a concentration-dependent decrease of sound velocity was observed, too (+48 to -12 m/s approximately 2.3-0.1 MPa, for 10- to 100-microM tubulin). This decrease was interpreted by a nematic phase transition of the actin filaments and microtubules with increasing concentration. 2 mM ATP (when compared to 0.2 mM ATP) increased polymerization rate, final viscosity and elastic modulus of f-actin (17 microM). The actin-binding glycolytic enzyme hexokinase also accelerated the polymerization rate and final viscosity but elastic modulus (2.26 GPa) was less than for f-actin polymerized in presence of 0.2 mM ATP (2.28 GPa).  (+info)

Cardiac microvascular endothelial cells express alpha-smooth muscle actin and show low NOS III activity. (6/917)

We established a culture system of porcine coronary microvascular endothelial cells (MVEC) with high cellular yield and purity >98%. Endothelial origin was confirmed by immunostaining, immunoblotting and fluorescence-activated cell sorter (FACS) analysis using low-density lipoprotein uptake, CD31, von Willebrand factor, and the lectin Dolichos biflorus agglutinin. MVEC were positive for alpha-smooth muscle actin in culture and in myocardium, as confirmed by FACS. Of the primary MVEC, approximately 30% expressed nitric oxide synthase (NOS) III in numbers decreasing from the first passage (6 +/- 1%) to the second passage (4 +/- 1%; P < 0.001 vs. primary isolates), whereas approximately 100% of aortic endothelial cells (AEC) expressed NOS III. In AEC, NOS III activity (pmol citrulline. mg protein-1. min-1) was 80 +/- 10 and was nearly abolished in the absence of calcium (5 +/- 1, P < 0.001). In primary MVEC, however, NOS III activity in the presence and absence of calcium was 20 +/- 4 and 25 +/- 5, respectively. We conclude that cardiac MVEC, in contrast to AEC, contain alpha-smooth muscle actin, show low-grade NOS III activity, and provide a suitable in vitro system for the study of endothelial pathophysiology.  (+info)

Myotilin, a novel sarcomeric protein with two Ig-like domains, is encoded by a candidate gene for limb-girdle muscular dystrophy. (7/917)

The striated muscle sarcomeres are highly organized structures composed of actin (thin) and myosin (thick) filaments that slide past each other during contraction. The integrity of sarcomeres is controlled by a set of structural proteins, among which are titin, a giant molecule that contains several immunoglobulin (Ig)-like domains and associates with thin and thick filaments, and [alpha]-actinin, an actin cross-linking protein. Mutations in several sarcomeric and sarcolemmal proteins have been shown to result in muscular dystrophy and cardiomyopathy. On the other hand, the disease genes underlying several disease forms remain to be identified. Here we describe a novel 57 kDa cytoskeletal protein, myotilin. Its N-terminal sequence is unique, but the C-terminal half contains two Ig-like domains homologous to titin. Myotilin is expressed in skeletal and cardiac muscle, it co-localizes with [alpha]-actinin in the sarcomeric I--bands and directly interacts with [alpha]-actinin. The human myotilin gene maps to chromosome 5q31 between markers AFM350yB1 and D5S500. The locus of a dominantly inherited limb-girdle muscular dystrophy (LGMD1A) resides in an overlapping narrow segment, and a new type of distal myopathy with vocal cord and pharyngeal weakness (VCPMD) has been mapped to the same locus. The muscle specificity and apparent role as a sarcomeric structural protein raise the possibility that defects in the myotilin gene may cause muscular dystrophy.  (+info)

Postmortem proteolysis and calpain/calpastatin activity in callipyge and normal lamb biceps femoris during extended postmortem storage. (8/917)

The present experiment was conducted to determine whether calpastatin inhibits only the rate, or both the rate and extent, of calpain-induced postmortem proteolysis. Biceps femoris from normal (n = 6) and callipyge (n = 6) lamb was stored for 56 d at 4 degrees C. Calpastatin activity was higher (P < .05) in the callipyge muscle at 0 and 14 d postmortem, but not at 56 d postmortem. The activity of mu-calpain did not differ between normal and callipyge biceps femoris at 0 and 56 d postmortem (P > .05), but was higher at 14 d postmortem in the callipyge muscle (P < 0.05). The activity of m-calpain was higher in the callipyge muscle (P < 0.05). Western blot analyses of titin, nebulin, dystrophin, myosin heavy chain, vinculin, alpha-actinin, desmin, and troponin-T indicated that postmortem proteolysis was less extensive in callipyge than in normal biceps femoris at all postmortem times. The results of this experiment indicate that calpastatin inhibits both the rate and extent of postmortem proteolysis.  (+info)

University of Helsinki, Faculty of Biosciences, Department of Biological and Environmental Sciences, Division of genetics and Institute of Biotechnology. The actin cytoskeleton is essential for a large variety of cell biological processes. Actin exists in either a monomeric or a filamentous form, and it is very important for many cellular functions that the local balance between these two actin populations is properly regulated. A large number of proteins participate in the regulation of actin dynamics in the cell, and twinfilin, one of the proteins examined in this thesis, belongs to this category. The second level of regulation involves proteins that crosslink or bundle actin filaments, thereby providing the cell with a certain shape. α-Actinin, the second protein studied, mainly acts as an actin crosslinking protein. Both proteins are conserved in organisms ranging from yeast to mammals. In this thesis, the roles of twinfilin and α-actinin in development were examined using Drosophila ...

Actinin alpha (pan), 0.1 mg. The spectrin gene family encodes a diverse group of cytoskeletal proteins that include spectrins, dystrophins and α-actinins.
Since Uzgiris and Kornberg showed that lipid monolayers formed excellent substrates for 2-D crystallization of proteins and macromolecular assemblies. We are using this technique to crystallize cytoskeletal proteins and their complexes. One of these molecules currently being studied is the actin crosslinking protein alpha-actinin. 2-D crystals of alpha-actinin have been formed on positively charged lipid monolayers. In addition, paracrystalline aggregates of F-actin and the complex between F-actin and α-actinin have also been formed on these same lipid monolayers. The technology for formation of 2-D paracrystalline bundles of F-actin on lipid monolayers makes it possible to study additional complexes between F-actin and its crosslinkers which hitherto had formed 3-D gels or bundles. The image to the right was published from Biophys. J. 67, 1976-1983 in 1994.. ...

Histone lysine methylation is considered to be a relatively stable modification associated with important functions in epigenetic gene control and for organizing chromatin domains. Genes encoding mammalian homologues of the Drosophila suppressor of PEV Su(var)3-9 were the first shown to encode proteins with histone lysine methyl-transferase (HKMT) activity. A hallmark signature of this class of proteins is the evolutionary conserved SET-domain found in numerous chromatin regulators, and was named for its occurrence in genes encoding three such regulators in Drosophila, namely Su(var)3-9, E(z) and trithorax. Here we describe the characterization of a putative SET-domain gene in Drosophila melanogaster, G9a. The gene encodes a protein of 1637 amino acids with similar domain architecture as the mammalian homologue of same name. Whole mount in situ hybridization shows that the gene is maternal and immunostaining shows nuclear localization of DmG9a. A yeast two-hybrid screening revealed that DmG9a ...
The proband (II-15) was an 82-year-old man with mild, asymmetrical LV hypertrophy localized to the basal and midseptum, marked biatrial dilatation, and a restrictive LV filling pattern with preserved systolic function. He had been diagnosed with nonobstructive HCM almost 3 decades earlier and followed at our institution since 2005. Remarkably, he had a history of paroxysmal AF that presented at the age of 30, which subsequently evolved into permanent AF with advanced AV block, requiring VVI pacing at the age of 68 (Figure 2). In 2008, he proved to be negative for mutations in the coding regions and splice sites of the 8 most prevalent sarcomere genes. Despite his early onset of disease manifestations and adverse cardiac remodeling, consistent with restrictive evolution of HCM, he remained fully active with only mild functional limitation (functional class New York Heart Association class II). Furthermore, he remained free from cardioembolic complications although he repeatedly refused treatment ...

Deficiency of the fast-twitch muscle protein alpha-actinin-3 due to homozygosity for a nonsense polymorphism (R577X) in the ACTN3 gene is common in humans. alpha-Actinin-3 deficiency (XX) is associated with reduced muscle strength/power and enhanced endurance performance in elite athletes and in the general population. The association between R577X and loss in muscle mass and function (sarcopenia) has previously been investigated in a number of studies in elderly humans. The majority of studies report loss of ACTN3 genotype association with muscle traits in the elderly, however, there is some indication that the XX genotype may be associated with faster muscle function decline. To further explore these potential age-related effects and the underlying mechanisms, we examined the effect of alpha-actinin-3 deficiency in aging male and female Actn3 knockout (KO) mice (2, 6, 12, and 18 months). Our findings support previous reports of a diminished influence of ACTN3 genotype on muscle performance in the
Alpha-actinin (alpha-actinin-2) is a protein which links the NR1 and NR2B subunits of N-methyl-D-aspartate (NMDA) glutamate receptors to the actin cytoskeleton. Because of the importance of NMDA receptors in modulating the function of the striatum, we have examined the localization of alpha-actinin-2 protein and mRNA in striatal neurons, and its biochemical interaction with NMDA receptor subunits present in the rat striatum. Using an alpha-actinin-2-specific antibody, we found intense immunoreactivity in the striatal neuropil and within striatal neurons that also expressed parvalbumin, calretinin and calbindin. Conversely, alpha-actinin-2 immunoreactivity was not detected in neurons expressing choline acetyltransferase and neuronal nitric oxide synthase. Dual-label in situ hybridization revealed that the highest expression of alpha-actinin-2 mRNA is in substance P-containing striatal projection neurons. The alpha-actinin-2 mRNA is also present in enkephalinergic projection neurons and ...

Dictyostelium alpha-actinin is a Ca(2+)-regulated F-actin cross-linking protein. To test the inhibitory function of the two EF hands, point mutations were introduced into either one or both Ca(2+)-binding sites. After mutations, the two EF hands were distinguishable with respect to their regulatory activities. Inactivation of EF hand I abolished completely the F-actin cross-linking activity of Dictyostelium discoideum alpha-actinin but Ca2+ binding by EF hand II was still observed in a 45Ca2+ overlay assay. In contrast, after mutation of EF hand II the molecule was still active and inhibited by Ca2+; however, approximately 500-fold more Ca2+ was necessary for inhibition and 45Ca2+ binding could not be detected in the overlay assay. These data indicate that EF hand I has a low affinity for Ca2+ and EF hand II a high affinity, implying a regulatory function of EF hand I in the inhibition of F-actin cross-linking activity. Biochemical data is presented which allows us to distinguish two functions ...

Our previous series of studies have shown that l-afadin is essential for the colocalization and compact clustering of nectin with E-cadherin at cell-cell AJs and proper organization of E-cadherin-based cell-cell AJs (Ikeda et al. 1999; Takahashi et al. 1999; Miyahara et al. 2000). Extending these earlier observations, we have shown here that the COOH-terminal half of α-catenin is, furthermore, essential for this colocalization. This colocalization is not mediated through the cytoplasmic region of E-cadherin or β-catenin. α-Catenin directly interacts with vinculin and α-actinin through the NH2-terminal half (Knudsen et al. 1995; Nieset et al. 1997; Watabe-Uchida et al. 1998; Imamura et al. 1999) and with ZO-1 through the COOH-terminal half (Itoh et al. 1997; Imamura et al. 1999). All of these α-catenin-binding proteins directly interact with F-actin (Burridge and Feramisco 1982; Menkel et al. 1994; Johnson and Craig 1995; Itoh et al. 1997; Fanning et al. 1998). The present results show that ...
To examine the function of CRP2 in vivo, we generated Csrp2−/− mice by targeted mutation. The LIM domains of CRP2 mediate interactions with its binding partners including zyxin, α-actinin, and CRP2BP.12,19,30 Thus, we targeted the first LIM domain by disrupting exon 3, the largest coding exon. No message was detected in Csrp2−/− mouse RNA when exon 3 was used as a probe, although a smaller transcript was detected by RT-PCR. Nevertheless, no CRP2 was detected in protein isolated from Csrp2−/− mouse aorta by Western blot analysis using CRP2(91-98) antiserum. Furthermore, immunostaining of aortic sections with CRP2(93-108) antiserum did not detect CRP2 expression in Csrp2−/− mice. We cannot exclude the possibility that a truncated protein could be generated because the two antisera used in this study were against epitopes C-terminal to those encoded by exon 2. However, even if the truncated transcript were translated, it would not encode either LIM domain due to a frame shift. ...

This paper provides a comprehensive explanation of striated muscle mechanics and contraction on the basis of filament rotations. Helical proteins, particularly the coiled-coils of tropomyosin, myosin and α-actinin, shorten their H-bonds cooperatively and produce torque and filament rotations when the Coulombic net-charge repulsion of their highly charged side-chains is diminished by interaction with ions. The classical
Heterogeneity of SMC is a well-known phenomenon. The interpretation, however, of the morphologic phenotype as well as the functional implications of the expression of differentiation markers is subject to much debate. The data are derived from in vivo or in vitro studies. The material used varies from adult to neonatal to fetal vessels and cells from different animal species. The origin of the cultured cells can be from intima, inner or outer media, or the adventitia in both normal and diseased vessels.. The data from in vitro studies are largely reflected in in vivo studies. Proceeding from data in early fetal development, it has been shown that the SMC start to express SM α-actin17 followed by 1E12,20 an actinin marker, and smoothelin.21 Relative late differentiation markers are the already mentioned markers, such as SM22, calponin, h-caldesmon,7 and SM myosin.8 These are upregulated until the expression level of the mature vessel wall is reached.9 11 During this developmental period, there ...
Immunocytochemistry for confocal microscopy. Sections were blocked in 20% normal donkey serum (NDS; Jackson ImmunoResearch, West Grove, PA) in 0.05 m PBS, pH 7.4, then incubated in various combinations of primary antibodies for cortactin, α-actinin, synaptophysin, and VGLUT1 in PBS containing 2% NDS overnight at room temperature. After several washes, sections were incubated in secondary antibodies (anti-rabbit Cy3 for cortactin, anti-mouse FITC for synaptophysin and VGLUT1). Alexa Fluor-488 conjugated to phalloidin (Molecular Probes, Eugene, OR) was used for visualization of F-actin (Allison et al., 1998). For visualization of cell processes, we used the lipophilic dye 3,3′-dioctadecyloxacarbocyanidine perchlorate (DiO; Molecular Probes), which infiltrates the plasma membrane, labeling even the finest neuronal processes (for details, see Burette et al., 2002). After several washes, sections were mounted on glass slides, coverslipped in Vectashield (Vector Laboratories, Burlingame, CA) and ...

Things will be a lot different when we are older. Perhaps when your grandchild is born, right after they snip the umbilical cord, they will sequence their genome. Immediately, some computer will pick out genetic markers for specific disease states, and maybe a doctor (possibly some gene-ologist of sorts) will do a little bit of gene therapy to prevent the more serious diseases from developing. Perhaps for those really wealthy parents, a few more options may open for tweaking. If you dont like the hair colour your childs genes code for, just check the appropriate box and they can take care of that. What about sports? Would you prefer a power athlete, maybe a sprinter, or would you rather your child be tailored for endurance? For that option, perhaps they would look at tinkering with the ACTN3 gene, which encodes the muscle fiber protein alpha-actinin-3. As it turns out, you could probably already predict genetic predisposition of muscles for either power or endurance. There is evidence for certain

Many eukaryotes have long slender motile cytoplasmic projections, called flagella. These are composed mainly of tubulin and shorter cilia, both of which are variously involved in movement, feeding, and sensation. These are entirely distinct from prokaryotic flagella. They are supported by a bundle of microtubules arising from a basal body, also called a kinetosome or centriole, characteristically arranged as nine doublets surrounding two singlets. Flagella also may have hairs, or mastigonemes, and scales connecting membranes and internal rods. Their interior is continuous with the cells cytoplasm. Microfilamental structures composed by actin and actin binding proteins, e.g., α-actinin, fimbrin, filamin are present in submembraneous cortical layers and bundles, as well. Motor proteins of microtubules, e.g., dynein or kinesin and actin, e.g., myosins provide dynamic character of the network. Centrioles are often present even in cells and groups that do not have flagella. They generally occur in ...
Clone REA199 recognizes CD144 (VE-Cadherin), a 120 KDa type II cadherin. Cadherins are cell adhesion molecules and mediate Ca2+ dependent homophilic interactions. CD144 contains five extracellular cadherin (EC) domains and like other cadherins can interact directly via its C-terminus with cytoplasmic proteins such as β-catenin, plaktoglobin, and p120. Plaktoglobin und β-catenin bind to α-catenin, which in turn interacts with several actin-binding proteins, α-actinin, ajuba, zonula occludens-1 (ZO-1). Further indirect interactions of CD144 with partners such as SHP-2, VEGFR-2, Csk, and PAR-3, 6 allows CD144 to not only regulate the stability and strength of cell adhesion but also to serve functions such as sensing of shear forces, anti-proliferative, and anti-apoptotic effects. Additional information: Clone REA199 displays negligible binding to Fc receptors. - Ireland

Methods and Results: Distribution of Islet-1+ cells in adult heart was investigated using transgenic mice with nuclear β-galactosidase inserted into the Islet-1 locus. nLacZ-positive cells were only present in 3 regions of the adult heart: clusters in the interatrial septum, scattered within the wall of the great vessels, and a strictly delimited cluster between right atrium and superior vena cava. Islet-1+ cells in the first type of clusters coexpressed markers for parasympathetic neurons. Positive cells in the great arteries coexpressed smooth muscle actin and β-myosin heavy chain, indicating a smooth muscle cell identity. Very few Islet-1+ cells within the outflow tract expressed the cardiomyocyte marker α-actinin. Islet-1+ cells in the right atrium coexpressed the sinoatrial node pacemaker cell marker HCN4. Cell number and localization remained unchanged between 1 to 18 months of age. Consistently Islet-1 mRNA was detected in human sinoatrial node. Islet-1+ cells could not be detected in ...
Identification, characterization, and synthesis of peptide epitopes and a recombinant six-epitope protein for Trichomonas vaginalis serodiagnosis J F Alderete, Calvin J NeaceSchool of Molecular Biosciences, College of Veterinary Medicine, Washington State University, Pullman, WA, USAAbstract: There is a need for a rapid, accurate serodiagnostic test useful for both women and men infected by Trichomonas vaginalis, which causes the number one sexually transmitted infection (STI). Women and men exposed to T. vaginalis make serum antibody to fructose-1,6-bisphosphate aldolase (ALD), α-enolase (ENO), and glyceraldehyde-3-phosphate dehydrogenase (GAP). We identified, by epitope mapping, the common and distinct epitopes of each protein detected by the sera of women patients with trichomonosis and by the sera of men highly seropositive to the immunogenic protein α-actinin (positive control sera). We analyzed the amino acid sequences to determine the extent of identity of the epitopes of each protein

During chicken skeletal myogenesis in tissue culture, filamin is found on stress fibers in myoblasts and early myotubes. Approximately one day after fusion and shortly before [alpha]-actinin transits to Z lines, filamin disappears from the cells. The disappearance of filamin is correlated with a cessation of its synthesis. Approximately six days after fusion, filamin reappears at the Z lines of myogenic cells, shortly before desmin and vimentin transit to the Z line. In adult muscle, filamin is found at the periphery of the Z disk, along with desmin and vimentin. Peptide map analysis of the various filamins shows that gizzard and fibroblast filamins are identical while myoblast filamin is quite similar to these two filamins. Cultured myotube and adult myofibril filamins are virtually identical to each other and are quite different polypeptides when compared to gizzard, fibroblast and myoblast filamins. Analysis of terminally differentiated slow and fast muscle shows that both muscle types ...
Chromaffin cells of the adrenal medulla synthesize, store and secrete catecholamines. These cells contain numerous electron-dense secretory granules which discharge their contents into the extracellular space by exocytosis. The subplasmalemmal area of the chromaffin cell is characterized by the presence of a highly organized cytoskeletal network. F-Actin seems to be exclusively localized in this area and together with specific actin-binding proteins forms a dense viscoelastic gel; fodrin, vinculin and caldesmon, three actin cross-linking proteins, and gelsolin, an actin-severing protein, are found in this subplasmalemmal region. Since fodrin-, caldesmon- and alpha-actinin-binding sites exist on secretory granule membranes, actin filaments can also link secretory granules. Chromaffin granules can be entrapped in this subplasmalemmal lattice and thus the cytoskeleton acts as a barrier preventing exocytosis. When cells are stimulated, molecular rearrangements of the subplasmalemmal cytoskeleton ...

Methods. O-GlcNAcylated proteins were identified by two-dimensional gel electrophoresis, immunoblotting and peptide mass fingerprinting. The level of O-GlcNAcylation of these proteins was examined by immunoprecipitation, immunoblotting and in situ Proximity Ligation Assay (PLA). Results: O-GlcNAcylated ...
Inherited thrombocytopenias (ITs) are a heterogeneous group of syndromic and nonsyndromic diseases caused by mutations affecting different genes. Alterations of ACTN1, the gene encoding for alpha-actinin 1, have recently been identified in a few families as being responsible for a mild form of IT (ACTN1-related thrombocytopenia; ACTN1-RT). To better characterize this disease, we screened ACTN1 in 128 probands and found 10 (8 novel) missense heterozygous variants in 11 families. Combining bioinformatics, segregation, and functional studies, we demonstrated that all but 1 amino acid substitution had deleterious effects. The clinical and laboratory findings of 31 affected individuals confirmed that ACTN1-RT is a mild macrothrombocytopenia with low risk for bleeding. Low reticulated platelet counts and only slightly increased serum thrombopoietin levels indicated that the latest phases of megakaryopoiesis were affected. Given its relatively high frequency in our cohort (4.2%), ACTN1-RT has to be ...
