Coatomer subunit gamma ; 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 (899 aa ...

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 ...

Recently, Lanoix et al. 1999 have analyzed the resident protein (glycosyltransferase) content of an uncoated membrane fraction produced from Golgi membranes in vitro (in the presence of GTP) that is thought to be derived from COPI-coated vesicles, and compared this with bona fide COPI-coated vesicles prepared with GTPγS. They report (Table IV in Lanoix et al., 1999) a 9.6-fold higher concentration (protein/phospholipid) of NAGT I and a 4.8-fold higher concentration of Man II, in the uncoated (GTP) vesicles than in the starting Golgi fraction and an exclusion of residents in the GTPγS -prepared coated vesicles. There was no corresponding enrichment in anterograde-directed cargo in the GTP-produced uncoated vesicles (1.7-fold for pIgR) or in bona fide COP I-coated vesicles made with GTPγS (1.2-fold). In contradiction to this, Nickel et al. 1998 analyzed bona fide coated COPI vesicles produced in the presence of GTP versus GTPγS, and report that anterograde-directed cargo is up to 50-fold more ...

p,Coat protein I (COPI)-coated vesicles mediate retrograde transport from the Golgi to the endoplasmic reticulum (ER), as well as transport within the Golgi. Major progress has been made in defining the structure of COPI coats, in vitro and in vivo, at resolutions as high as 9 Å. Nevertheless, important questions remain unanswered, including what specific interactions stabilize COPI coats, how COPI vesicles recognize their target membranes, and how coat disassembly is coordinated with vesicle fusion and cargo delivery. Here, we use X-ray crystallography to identify a conserved site on the COPI subunit α-COP that binds to flexible, acidic sequences containing a single tryptophan residue. One such sequence, found within α-COP itself, mediates α-COP homo-oligomerization. Another such sequence is contained within the lasso of the ER-resident Dsl1 complex, where it helps mediate the tethering of Golgi-derived COPI vesicles at the ER membrane. Together, our findings suggest that α-COP ...

Phosphatidylinositol-4-phosphate-binding protein that links Golgi membranes to the cytoskeleton and may participate in the tensile force required for vesicle budding from the Golgi. Thereby, may play a role in Golgi membrane trafficking and could indirectly give its flattened shape to the Golgi apparatus. May also bind to the coatomer to regulate Golgi membrane trafficking. May play a role in anterograde transport from the Golgi to the plasma membrane and regulate secretion. Has also been involved in the control of the localization of Golgi enzymes through interaction with their cytoplasmic part. May play an indirect role in cell migration. Has also been involved in the modulation of mTOR signaling. May also be involved in the regulation of mitochondrial lipids biosynthesis (By similarity).

Initially one meets the parents of the disappeared: Jully Lee as a mother who let go of her young sons hand just a moment only to find him gone, Adrian Gonzalez as the young father who gave in and let his son walk home from school only to have him never arrive. Julie Cardia is the frustrated mom who tossed her rebellious teenaged daughter from home only to have her vanish, while Tracey A. Leigh and Leandro Cano as loving parents of an autistic boy who disappeared out an open door when his mom fell asleep on the couch. Each creates a carefully crafted portrait, as each character makes an individual passionate plea for understanding, wrestles with horrific guilt, and slowly, specifically, finds a way to carry the burden of loss.. Balanced against these, the play concentrates on the family of Jason, whose divorced, meth-addicted mother, Nicky, finds him useful only as a crutch, and whose father, Mark, recently released from a prison sentence associated with Jasons actions and, along with his ...

In addition to the better characterized COPI-dependent retrograde Golgi-to-ER pathway, a second COPI-independent pathway has also been identified. This pathway is RAB6 dependent and transports cargo such as glycosylation enzymes and Shiga and Shiga-like toxin through tubular carriers rather than vesicles (White et al, 1999; Girod et al, 1999; reviewed in Heffernan and Simpson, 2014). In the absence of a COPI coat, the membrane curvature necessary to initiate tubulation may be provided through the action of phospholipase A, which hydrolyzes phospholipids at the sn2 position to yield lysophospholipids. This activity is countered by lysophospholipid acyltransferases, and the balance of these may influence whether transport tubules or transport vesicles form (de Figuiredo et al, 1998; reviewed in Bechler et al, 2012). RAB6-dependent tubules also depend on the dynein-dynactin motor complex and the hoomodimeric Bicaudal proteins (Matanis et al, 2002; Yamada et al, 2013; reviewed in Heffernan and ...

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., ...

SCYL1 binds COP1 vesicles that mediate retrograde Golgi-to ER transport, through an SCYL1-specific RKLD motif at the extreme C terminus [2]. Knockdown of SCYL1 disrupts Golgi morphology and blocks retrograte COPI-mediated transport from Golgi to ER [3]. The Golgi-localized Gorab protein (aka NTKL-BP1, SCYL-BP1) was found as a interactor of mouse Scyl1 by Y2H and coIP [4]. The yeast SCYL1, Cex1, also has several trafficking-associated physical and genetic interactors, including YPT6 (Golgi fusion of late endosome vesicles), COG5 and COG6 (fusion of vesicles to Golgi), several COPI complex members (COP1, SEC27, SEC29, RET2, UBP5 and BRE5 (ER-Golgi transport), and RGP1 and RIC1 (Golgi-to-ER transport) (BioGrid). SCYL2 appears to act a a different point in trafficking - the endocytosis and trafficking of surface proteins. Human SCYL2 (aka CVAK104) binds clathrin and the plasma membrane adaptor complex, AP2 [5]. Yeast SCYL2 (Cex1) was also found in a genetic screen for modifiers of a clathrin mutant ...

The mammalian Golgi complex is composed of stacks of flattened cisternae linked through tubules to form a contiguous juxtanuclear ribbon. The stacked cisternae reflect the compartmentalization of Golgi enzymes for the processing of transiting cargo (Mellman and Simons, 1992; Puthenveedu and Linstedt, 2005). Cargo movement through the stack has been variously suggested to occur in vesicles, in maturing cisternae, or by tubular connections between cisternae (Malhotra et al., 1989; Mollenhauer and Morre, 1991; Glick et al., 1997; Allan and Balch, 1999; Pelham and Rothman, 2000; Trucco et al., 2004). Although not exclusive of other processes, maturation has gained recent support (Emr et al., 2009). This model starts with the creation of cargo-containing cis-Golgi cisternae. The cargo stays within these cisternae and is sequentially processed when the cis enzymes are replaced with medial enzymes, which are subsequently replaced with trans enzymes. As cisternae progress through the Golgi stack, this ...

Regarding the biogenesis of peroxisomes various concepts have been postulated. Based on morphological data that demonstrated close spatial relationships between peroxisomes and the ER, Novikoff and Novikoff (44) favored the idea that new peroxisomes are formed by budding and fission from the ER. However, a series of biochemical studies initiated by de Duve and coworkers (36, 51) in the early 1970s, focusing on the biogenetic route of catalase as a peroxisomal marker, did not reveal an ER involvement in the import of catalase. Subsequent findings of Goldman and Blobel (19) and particularly the group of Lazarow and coworkers (52, 54) confirmed this view demonstrating that peroxisomal matrix proteins, such as catalase, urate oxidase, and enzymes of the peroxisomal β-oxidation pathway, are synthesized on free polyribosomes and thus are imported posttranslationally. Accordingly, Goldman and Blobel (19) postulated a model in which peroxisomal matrix proteins are found in nascent peroxisomes, whereas ...

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 ...

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.

Newly synthesized proteins and lipids are transported across the Golgi complex via different mechanisms whose respective roles are not completely clear. We previously identified a non-vesicular intra-Golgi transport pathway for glucosylceramide (GlcCer)--the common precursor of the different series of glycosphingolipids-that is operated by the cytosolic GlcCer-transfer protein FAPP2 (also known as PLEKHA8) (ref. 1). However, the molecular determinants of the FAPP2-mediated transfer of GlcCer from the cis-Golgi to the trans-Golgi network, as well as the physiological relevance of maintaining two parallel transport pathways of GlcCer--vesicular and non-vesicular--through the Golgi, remain poorly defined. Here, using mouse and cell models, we clarify the molecular mechanisms underlying the intra-Golgi vectorial transfer of GlcCer by FAPP2 and show that GlcCer is channelled by vesicular and non-vesicular transport to two topologically distinct glycosylation tracks in the Golgi cisternae and the trans-Golgi
