It is involved in transport of vesicles between the ENDOPLASMIC RETICULUM and the GOLGI APPARATUS.COP-Coated Vesicles: TRANSPORT VESICLES formed when cell-membrane coated pits (COATED PITS, CELL-MEMBRANE) invaginate and pinch off. The outer surface of these vesicles is covered with a lattice-like network of COP (coat protein complex) proteins, either COPI or COPII. COPI coated vesicles transport backwards from the cisternae of the GOLGI APPARATUS to the rough endoplasmic reticulum (ENDOPLASMIC RETICULUM, ROUGH), while COPII coated vesicles transport forward from the rough endoplasmic reticulum to the Golgi apparatus.ADP-Ribosylation Factor 1: ADP-RIBOSYLATION FACTOR 1 is involved in regulating intracellular transport by modulating the interaction of coat proteins with organelle membranes in the early secretory pathway. It is a component of COAT PROTEIN COMPLEX I. This enzyme was formerly listed as EC 3.6.1.47.Golgi Apparatus: A stack of flattened vesicles that functions in posttranslational processing and sorting of proteins, receiving them from the rough ENDOPLASMIC RETICULUM and directing them to secretory vesicles, LYSOSOMES, or the CELL MEMBRANE. The movement of proteins takes place by transfer vesicles that bud off from the rough endoplasmic reticulum or Golgi apparatus and fuse with the Golgi, lysosomes or cell membrane.

They play a role in the intracellular transport of molecules contained within membrane vesicles. Vesicular transport proteins are distinguished from MEMBRANE TRANSPORT PROTEINS, which move molecules across membranes, by the mode in which the molecules are transported.Coated Vesicles: Vesicles formed when cell-membrane coated pits (COATED PITS, CELL-MEMBRANE) invaginate and pinch off. The outer surface of these vesicles are covered with a lattice-like network of coat proteins, such as CLATHRIN, coat protein complex proteins, or CAVEOLINS.Endoplasmic Reticulum: A system of cisternae in the CYTOPLASM of many cells. In places the endoplasmic reticulum is continuous with the plasma membrane (CELL MEMBRANE) or outer membrane of the nuclear envelope. If the outer surfaces of the endoplasmic reticulum membranes are coated with ribosomes, the endoplasmic reticulum is said to be rough-surfaced (ENDOPLASMIC RETICULUM, ROUGH); otherwise it is said to be smooth-surfaced (ENDOPLASMIC RETICULUM, SMOOTH).

Segregation of COPI-rich and anterograde-cargo-rich domains in endoplasmic-reticulum-to-Golgi transport complexes. (1/177)

Membrane traffic between the endoplasmic reticulum (ER) and the Golgi complex is regulated by two vesicular coat complexes, COPII and COPI. COPII has been implicated in the selective packaging of anterograde cargo into coated transport vesicles budding from the ER [1]. In mammalian cells, these vesicles coalesce to form tubulo-vesicular transport complexes (TCs), which shuttle anterograde cargo from the ER to the Golgi complex [2] [3] [4]. In contrast, COPI-coated vesicles are proposed to mediate recycling of proteins from the Golgi complex to the ER [1] [5] [6] [7]. The binding of COPI to COPII-coated TCs [3] [8] [9], however, has led to the proposal that COPI binds to TCs and specifically packages recycling proteins into retrograde vesicles for return to the ER [3] [9]. To test this hypothesis, we tracked fluorescently tagged COPI and anterograde-transport markers simultaneously in living cells. COPI predominated on TCs shuttling anterograde cargo to the Golgi complex and was rarely observed on structures moving in directions consistent with retrograde transport. Furthermore, a progressive segregation of COPI-rich domains and anterograde-cargo-rich domains was observed in the TCs. This segregation and the directed motility of COPI-containing TCs were inhibited by antibodies that blocked COPI function. These observations, which are consistent with previous biochemical data [2] [9], suggest a role for COPI within TCs en route to the Golgi complex. By sequestering retrograde cargo in the anterograde-directed TCs, COPI couples the sorting of ER recycling proteins [10] to the transport of anterograde cargo.  (+info)

GTP hydrolysis by arf-1 mediates sorting and concentration of Golgi resident enzymes into functional COP I vesicles. (2/177)

Upon addition of GTPgammaS to in vitro budding reactions, COP I vesicles form but retain their coat, making them easy to isolate and analyze. We have developed an in vitro budding assay that reconstitutes the formation of COP I-derived vesicles under conditions where GTP hydrolysis can occur. Once formed, vesicles are uncoated and appear functional as they fuse readily with acceptor membranes. Electron microscopy shows a homogeneous population of uncoated vesicles that contain the medial/trans Golgi enzyme alpha1, 2-mannosidase II. Biochemical quantitation of vesicles reveals that resident Golgi enzymes are up to 10-fold more concentrated than in donor membranes, but vesicles formed in the presence of GTPgammaS show an average density of resident Golgi enzymes similar to that seen in donor membranes. We show that the sorting process is mediated by the small GTPase arf-1 as addition of a dominant, hydrolysis-deficient arf-1 (Q)71(L) mutant produced results similar to that of GTPgammaS. Strikingly, the average density of the anterograde cargo protein, polymeric IgA receptor, in COP I-derived vesicles was similar to that found in starting membranes and was independent of GTP hydrolysis. We conclude that hydrolysis of GTP bound to arf-1 promotes selective segregation and concentration of Golgi resident enzymes into COP I vesicles.  (+info)

Studies on the inhibition of endosome fusion by GTPgammaS-bound ARF. (3/177)

Using a cell free assay, we have previously shown that ARF is not required for endosome fusion but that inhibition of fusion by GTPgammaS is dependent on a cytosolic pool of ARFs. Since ARF is proposed to function in intracellular membrane traffic by promoting vesicle biogenesis, and components of clathrin- and COP-coated vesicles have been localized on endosomal structures, we investigated whether ARF-mediated inhibition of early endosome fusion involves the recruitment or irreversible association of these proteins onto endosomal membranes. We now report that depletion of components of clathrin coated vesicles (clathrin, AP-1 and AP-2) or COPI vesicles (beta COP) does not affect the capacity of GTPgammaS-activated ARF to inhibit endosome fusion. Inhibition of fusion by activated ARF is also independent of endosomal acidification since assays performed in the presence of the vacuolar ATPase inhibitor bafilomycin A1 are equally sensitive to GTPgammaS-bound ARF. Finally, in contrast to reported effects on lysosomes, we demonstrate that ARF-GTPgammaS does not induce endosomal lysis. These combined data argue that sequestration of known coat proteins to membranes by activated ARF is not involved in the inhibition of early endosome fusion and that its capacity to inhibit fusion involves other specific interactions with the endosome surface. These results contrast with the mechanistic action of ARF on intra-Golgi transport and nuclear envelope assembly.  (+info)

Mutation of the yeast epsilon-COP gene ANU2 causes abnormal nuclear morphology and defects in intracellular vesicular transport. (4/177)

Previously we reported an original method of visualizing the shape of yeast nuclei by the expression of green fluorescent protein (GFP)-tagged Xenopus nucleoplasmin in Saccharomyces cerevisiae. To identify components that determine nuclear structure, we searched for mutants exhibiting abnormal nuclear morphology from a collection of temperature-sensitive yeast strains expressing GFP-tagged nucleoplasmin. Four anu mutant strains (anu1-1, 2-1, 3-1 and 4-1; ANU=abnormal nuclear morphology) that exhibited strikingly different nuclear morphologies at the restrictive temperature as compared to the wild-type were isolated. The nuclei of these mutants were irregularly shaped and often consisted of multiple lobes. ANU1, 3 and 4 were found to encode known factors Sec24p, Sec13p and Sec18p, respectively, all of which are involved in the formation or fusion of intracellular membrane vesicles of protein transport between the endoplasmic reticulum (ER) and the Golgi apparatus. On the other hand, ANU2 was not well characterized. Disruption of ANU2 (delta anu2) was not lethal but conferred temperature-sensitivity for growth. Electron microscopic analysis of anu2-1 cells revealed not only the abnormal nuclear morphology but also excessive accumulation of ER membranes. In addition, both anu2-1 and delta anu2 cells were defective in protein transport between the ER and the Golgi, suggesting that Anu2p has an important role in vesicular transport in the early secretory pathway. Here we show that ANU2 encodes a 34 kDa polypeptide, which shares a 20% sequence identity with the mammalian epsilon-COP. Our results suggest that Anu2p is the yeast homologue of mammalian epsilon-COP and the abrupt accumulation of the ER membrane caused by a blockage of the early protein transport pathway leads to alteration of nuclear morphology of the budding yeast cells.  (+info)

The sorting determinant guiding Hsp150 to the COPI-independent transport pathway in yeast. (5/177)

The COPI coatomer is thought to be required in yeast directly for retrograde transport from the Golgi to the endoplasmic reticulum (ER), and directly or indirectly for ER-to-Golgi transport. Unexpectedly, the secretory glycoproteins Hsp150 and invertase have been found not to require COPI for ER exit. The features according to which cargo proteins are selected for the COPI-independent pathway are not known. The ER form of Hsp150 has three distinct domains: an N-terminal fragment of 54 amino acids (subunit I) is followed by 11 repeats of a 19 amino acid peptide plus a unique C-terminal fragment of 114 amino acids (subunit II). By fusing heterologous proteins to different Hsp150 domains and expressing them in sec21-1 and sec21-3 mutants with temperature-sensitive mutations in the gamma-COPI subunit, we show here that the repeats of subunit II function as sorting determinants for COPI-independent ER exit. The C-terminal fragment of Hsp150 could be replaced by E. coli beta-lactamase or rat nerve growth factor receptor ectodomain (NGFRe), and subunit I could be deleted, without inhibiting COPI-independent transport. However, when the repetitive region was omitted and beta-lactamase was fused directly to the C terminus of subunit I, COPI was required for efficient ER exit. Mass spectroscopic analysis demonstrated that both subunit I and II of Hsp150 were extensively O-glycosylated, suggesting that the O-glycosylation pattern was not decisive for cargo selection.  (+info)

Membrane flow through the Golgi apparatus: specific disassembly of the cis-Golgi network by ATP depletion. (6/177)

Incubation of NRK cells for 30 to 45 minutes with 50 mM 2-deoxy-D-glucose (DOG) in glucose and pyruvate-free medium results in depletion of the cellular ATP pool and in specific disassembly of the cis-Golgi network (CGN), with the stack of Golgi cisternae (SGC) and the trans-Golgi network (TGN) remaining intact and sensitive to BFA. The disassembly of the CGN is mediated by long tubular structures extending outwards from the Golgi complex and involves microtubules. Upon removal of DOG and addition of glucose and pyruvate to the culture medium, the morphology of the CGN is slowly reestablished. Reconstruction of the CGN involves COPI/COPII-positive vesicles that resume the transport of proteins and in particular of CGN membrane proteins out of the ER. Exit of CGN membrane proteins from the ER is insensitive to BFA. In cells pretreated with nocodazole, the CGN membrane proteins are transported to the vicinity of the SGC fragments dispersed throughout the cytoplasm. Ultrastructural studies of cells engaged in the reconstruction of the CGN revealed that the CGN cisterna emerge as tubular structures extending from 0.2-0.3 microm uncoated vesicles prior to their organization on the cis-side of the SGC.  (+info)

Yeast ER-Golgi v-SNAREs Bos1p and Bet1p differ in steady-state localization and targeting. (7/177)

Vesicle specific SNAP receptors (v-SNAREs) Bos1p and Bet1p are involved in targeting of anterograde vesicles between the endoplasmic reticulum (ER) and early Golgi of Saccharomyces cerevisiae. To analyze factors that influence the targeting of these proteins, alpha-factor tagged versions of Bos1p and Bet1p were employed. The alpha-factor can be cleaved off by the Kex2p protease as soon as the hybrid proteins reach the late Golgi compartment. The data obtained by monitoring of Kex2p cleavage, by immunofluorescence microscopy and cell fractionation showed that Bos1-alpha and Bet1-alpha have different cellular localization and dynamics. Bos1-alpha is an ER protein, which recycles between the Golgi and the ER in COPI-dependent manner. Bet1-alpha is an early Golgi protein and it does not change its localization under conditions when other recycling Golgi proteins can be trapped in the ER.  (+info)

gamma2-COP, a novel imprinted gene on chromosome 7q32, defines a new imprinting cluster in the human genome. (8/177)

We describe a novel imprinted gene, gamma 2-COP (nonclathrincoatprotein), identified in a search for expressed sequences in human chromosome 7q32 where the paternally expressed MEST gene is located. gamma 2-COP contains 24 exons and spans >50 kb of genomic DNA. Like MEST, gamma 2-COP is ubiquitously transcribed in fetal and adult tissues. In fetal tissues, including skeletal muscle, skin, kidney, adrenal, placenta, intestine, lung, chorionic plate and amnion, gamma 2-COP is imprinted and expressed from the paternal allele. In contrast to the monoallelic expression observed in these fetal tissues, biallelic expression was evident in fetal brain and liver and in adult peripheral blood. Biallelic expression in blood is supported by the demonstration of gamma 2-COP transcripts in lymphoblastoid cell lines with maternal uniparental disomy 7. Absence of paternal gamma 2-COP transcripts during embryonic development may contribute to Silver-Russell syndrome. However, on mutation scanning the only gamma 2-COP mutation detected was maternally derived. Amino acid comparison of gamma2-COP protein revealed close relation to gamma-COP, a subunit of the coatomer complex COPI, suggesting a role of gamma2-COP in cellular vesicle traffic. The existence of distinct coatomer complexes could be the basis for the functional heterogeneity of COPI vesicles in retrograde and anterograde transport and/or in cargo selection. Together, gamma 2-COP and MEST constitute a novel imprinting cluster in the human genome that may contain other, as yet unknown, imprinted genes.  (+info)

Coat protein complex I (COPI) vesicles are involved in transport processes within the early secretory pathway (Bethune et al., 2006). For their biogenesis, the small GTPase ADP ribosylation factor 1 (Arf1) in its GDP-bound form is recruited to the Golgi membrane by dimeric transmembrane proteins of the p24 family (Gommel et al., 2001) or by interaction with membrin (Honda et al., 2005). The membrane-associated Arf guanine nucleotide exchange factor GBF1 catalyzes exchange of the bound GDP to GTP (Zhao et al., 2006). Arf1-GTP dissociates from the p24 proteins and is inserted into the Golgi membrane (Franco et al., 1996; Antonny et al., 1997) as a dimer (Beck et al., 2008) to recruit the heptameric protein complex coatomer (Palmer et al., 1993). Coatomer polymerization leads to the formation of a COPI-coated vesicle (Bremser et al., 1999; Reinhard et al., 1999). Arf GTPase-activating proteins (GAPs) catalyze hydrolysis of the GTP bound to Arf1 followed by dissociation of the coat (Tanigawa et al., ...
Small GTPases largely control membrane traffic, which is essential for the survival of all eukaryotes. Among the small GTP-binding proteins, ARF1 (ADP-ribosylation factor 1) and SAR1 (Secretion-Associated RAS super family 1) are commonly conserved among all eukaryotes with respect to both their functional and sequential characteristics. The ARF1 and SAR1 GTP-binding proteins are involved in the formation and budding of vesicles throughout plant endomembrane systems. ARF1 has been shown to play a critical role in COPI (Coat Protein Complex I)-mediated retrograde trafficking in eukaryotic systems, whereas SAR1 GTPases are involved in intracellular COPII-mediated protein trafficking from the ER to the Golgi apparatus. This review offers a summary of vesicular trafficking with an emphasis on the ARF1 and SAR1 expression patterns at early growth stages and in the de-etiolation process.
Microinjection of the slowly hydrolyzable GTP analogue GTP(gamma)S or the ectopic expression of a GTP restricted mutant of the small GTPase arf1 (arf1[Q71L]) leads to the rapid accumulation of COPI coated vesicles and buds in living cells. This effect is blocked at 15 degrees C and by microinjection of antibodies against (beta)-COP. Anterograde and retrograde membrane protein transport markers, which have been previously shown to be incorporated into COPI vesicles between the endoplasmic reticulum and Golgi complex, are depleted from the GTP(gamma)S or arf1[Q71L] induced COPI coated vesicles and buds. In contrast, in control cells 30 to 60% of the COPI carriers co-localize with these markers. These in vivo data corroborate recent in vitro work, suggesting that GTP(gamma)S and arf1[Q71L] interfere with the sorting of membrane proteins into Golgi derived COPI vesicles, and provide the first in vivo evidence for a role of GTP hydrolysis by arf1 in the sorting of cargo into COPI coated vesicles and ...

Cytokinesis is the final step of cell division, and results from the constriction of a contractile ring comprising F-actin and myosin fibers (Satterwhite and Pollard, 1992). Microtubule bundles known as the central spindle help position the actomyosin ring at the equator (Glotzer, 2001; Cao and Wang, 1996; Inoue et al., 2004). A protein complex called centralspindlin plays a key role in initiating contractile ring formation (DAvino et al., 2005; Mishima and Glotzer, 2003). Completion of cytokinesis is dependent not only on contractile ring formation, but also on vesicle transport (Glotzer, 2001; Albertson et al., 2005; Montagnac et al., 2008; Prekeris and Gould, 2008).. The delivery of membrane components to the cleavage furrow region of the equatorial plasma membrane is thought to involve two different vesicle transport pathways: the secretory pathway and the endocytic pathway. The Drosophila melanogaster secretory pathway involves several transport proteins. Syntaxin 5 (one of the SNAREs ...
COPE Full-Length MS Protein Standard (NP_009194), Labeled with [U- 13C6, 15N4]-L-Arginine and [U- 13C6, 15N2]-L-Lysine, was produced in human 293 cells (HEK293) with fully chemically defined cell culture medium to obtain incorporation efficiency at Creative-Proteomics. The product of this gene is an epsilon subunit of coatomer protein complex. Coatomer is a cytosolic protein complex that binds to dilysine motifs and reversibly associates with Golgi non-clathrin-coated vesicles. It is required for budding from Golgi membranes, and is essential for the retrograde Golgi-to-ER transport of dilysine-tagged proteins. Coatomer complex consists of at least the alpha, beta, beta, gamma, delta, epsilon and zeta subunits. Alternatively spliced transcript variants encoding different isoforms have been identified.
Oxidative Phosphorylation: The process starts when electron carriers NADH and FADH2 unload electrons slowly into the electron transport chain (ETC), which creates energy. As electrons flow down the ETC, they meet up with oxygen to form water and CO2 as byproducts. At the same time, hydrogen ions (H+) are released as NADH & FADH2 are oxidized. H+ ions are then pumped upstream through protein complexes I, III, & IV into the intermembrane, where they build up. As they begin to gather, potential energy is created in the form of a gradient. Those ions then flow downstream through an enzyme called ATP synthase, where they re-enter the matrix as ATP molecules ...

ARF GAP Lis a kind of important regulator of introcellular transport. Recently, a novel human gene has been found from a cDNA library of second trimester human fetal liver. The amino acid sequence encoded by the novel gene has 32% similarity to rat ARF1 GAP, was thus termed as ARFGAP3. Functional studies of the new gene were performed. The full-length cDNA of ARFGAP3 was amplified from the human total placenta RNA by RT-PCR technique, then subcloned into pGEM-T vector and sequenced. The RNA Master blot and multiple tissue Northern blot analysis were used to define the expression profile and the transcript size of ARFGAP3 in human tissues. It was shown that ARFGAP3 was strongly expressed in glands and testis and that ARFGAP3 mRNA existed as only one kind of transcript of 2.7 kb in various human tissues. Then, the expression and purification of the recombinant human ARFGAP3 (rhARFGAP3) were performed. It was demonstrated that rhARFGAP3 exhibited strong GTPase-activating protein ( GAP) activity ...

The coatomer is a cytosolic protein complex that binds to dilysine motifs and reversibly associates with Golgi non-clathrin-coated vesicles, which further mediate biosynthetic protein transport from the ER, via the Golgi up to the trans Golgi network. Coatomer complex is required for budding from Golgi membranes, and is essential for the retrograde Golgi-to-ER transport of dilysine-tagged proteins. In mammals, the coatomer can only be recruited by membranes associated to ADP-ribosylation factors (ARFs), which are small GTP-binding proteins; the complex also influences the Golgi structural integrity, as well as the processing, activity, and endocytic recycling of LDL receptors (By similarity).

This study shows a critical role for Asna1 in ensuring β-cell function. Loss of Asna1 in β-cells of mice results in pancreatic hypoinsulinemia, impaired insulin secretion, and early onset diabetes. Additionally, β-cells of Asna1β−/− mice showed impaired PM-to-TGN as well as Golgi-to-ER retrograde transport, ER stress, and mislocalization of Stx5 and Stx6. Of note, we also show that inhibition of retrograde transport at the level of EE-to-TGN in isolated islet and insulinoma cells results in impaired Golgi-to-ER retrograde transport, decreased insulin content, and ER stress. Thus, the findings provide evidence that Asna1 is required in β-cells to ensure retrograde transport, which in turn appears to be essential for ER homeostasis and proinsulin biogenesis. Additionally, the perturbed Golgi-to-ER retrograde transport in Retro-2-treated primary islets suggests that the impairment of this step in Asna1β−/− β-cells likely is secondary to the inhibition of retrograde transport at the ...

On page 1029, Supek et al. illustrate how a peripheral membrane protein organizes a coat protein complex involved in secretory vesicle formation.. The protein in question, yeast Sec16p, is an ER resident required in vivo for COPII-dependent vesicle budding. In vitro, Sec16p is not necessary for budding from liposomes reconstituted with pure cytosolic COPII proteins. However, this in vitro reaction depends on a nonhydrolyzable form of GTP, probably because the COPII coat falls apart when Sar1p (the initiator of coat assembly) hydrolyzes GTP. Until now, the function of Sec16p in liposome budding could not be tested, because the protein was difficult to purify. Supek et al. report conditions that stabilize Sec16p and have purified enough protein for in vitro studies. Microsomal membranes stripped of endogenous Sec16p were stimulated in vesicle budding by the purified. protein, but only in the presence of hydrolyzable GTP. Thus, the in vivo function of Sec16p may be either to slow GTP hydrolysis ...

As the debate surrounding the telcos has lately been focused on net neutrality, another issue that is a result of the lack of competition in the space has slipped back under the radar: naked DSL. Most of the telcos (Qwest being a notable exception) require that any customer who wants a DSL line also has to buy phone service from them as well. This is what allows them to claim they charge only $15 or whatever for a DSL line, but if you add in the phone service and additional fees it tends to be much higher. Its never made much sense that the telcos are so against just offering plain old naked DSL without the phone service. After all, for people who just want to use a mobile phone and/or VoIP, isnt that only going to encourage them to go to the competition who wont force them to bundle an unwanted service? Oh... right. There isnt much competition, which is what allows the telcos to get away with the bundle. For quite some time, theres been some pressure on SBC/AT&T to offer naked DSL in ...

Transition zones are associated with the Golgi stacks. They are close to each other. This makes sense because the communication is more efficient. Vesicles dont need to travel long distances and the existence of the Golgi apparatus itself depends on a continuous process of vesicle incoming. It has been observed that a new transition zone led quickly to the nearby formation of a new Golgi stack. On the contrary, if a transition zone disappears, the associated Golgi cisternae are also lost. Transition zones can fuse with others and one transition zone can be split in two. Their associated Golgi stacks match this behavior. Vesicles budding from the transition zones are COPII coated vesicles ( COPII: coat protein II; Figure 1). Several proteins are involved in the formation of this COPII molecular framework: Sec16, Sar1 GTPases, Sec23/24 and Sec13/31. In this order, they are assembled at the cytosolic surface of the transition zone membranes. Transition zones are the more suitable environments for ...

The final volume of Love in Focus is here! After the dramatic events of Volume 2, just who will our heroine end up dating (if anyone)? Everything is at stake, and friendships are muddled, as our protagonist comes to grips with her feelings… At the end of Volume 2 Mako was confessed to by childhood friend Kei, whom weve long known has had a crush on her. His confession is such a shock to Mako that she comes down with a fever! After recovering, she spends a week mulling over Keis words, debating if she sees him as a romantic interest or not. In the end Kei suggests that he and Mako begin dating on a trial basis, to see how things go. Mako agrees to this but its clear to Kei that her feelings arent necessarily in his favour. Elsewhere, Amemura is upset by news of Mako and Kei becoming a couple, but he tells Kei he has no intention of stealing her from him. Its an honest and noble comment from the more likeable love interest of the two. When not knee-deep in the romance, this volume of Love ...
