STRINGSTRING
ERV46 protein (Saccharomyces cerevisiae) - STRING interaction network
"ERV46" - Protein localized to COPII-coated vesicles, forms a complex with Erv41p in Saccharomyces cerevisiae
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

ERV46Protein localized to COPII-coated vesicles, forms a complex with Erv41p; involved in the membrane fusion stage of transport; Constituent of COPII-coated endoplasmic reticulum- derived transport vesicles. Required for efficient transport of a subset of secretory proteins to the Golgi. The C-terminal Phe-Tyr motif is required for exit from the endoplasmic reticulum. Facilitates retrograde transport from the Golgi to the endoplasmic reticulum (415 aa)    
Predicted Functional Partners:
ERV41
Protein localized to COPII-coated vesicles, forms a complex with Erv46p; involved in the membrane fusion stage of transport; has homology to human ERGIC2 (PTX1) protein; Constituent of COPII-coated endoplasmic reticulum- derived transport vesicles. Required for efficient transport of a subset of secretory proteins to the Golgi. The C-terminal Ile-Leu motif is required for exit from the endoplasmic reticulum. Facilitates retrograde transport from the Golgi to the endoplasmic reticulum (352 aa)

RTN1
ER membrane protein that interacts with Sey1p to maintain ER morphology; interacts with exocyst subunit Sec6p, with Yip3p, and with Sbh1p; null mutant has an altered ER morphology; member of the RTNLA (reticulon-like A) subfamily (295 aa)

ERO1
Thiol oxidase required for oxidative protein folding in the endoplasmic reticulum; Essential oxidoreductase that oxidizes proteins in the endoplasmic reticulum to produce disulfide bonds. Acts by oxidizing directly PDI1 isomerase through a direct disulfide exchange. Does not act as a direct oxidant of folding substrate, but relies on PDI1 to transfer oxidizing equivalent. Also able to oxidize directly the PDI related protein MPD2. Does not oxidize all PDI related proteins, suggesting that it can discriminate between PDI1 and related proteins. Reoxidation of ERO1 probably involves elect [...] (563 aa)

SAR1
GTPase, GTP-binding protein of the ARF family, component of COPII coat of vesicles; required for transport vesicle formation during ER to Golgi protein transport; Small GTPase component of the coat protein complex II (COPII) which promotes the formation of transport vesicles from the endoplasmic reticulum (ER). The coat has two main functions, the physical deformation of the endoplasmic reticulum membrane into vesicles and the selection of cargo molecules. SAR1 controls the coat assembly in a stepwise manner. Activated SAR1-GTP by SEC12 binds to membranes first and recruits the SEC23/2 [...] (190 aa)

COP1
Alpha subunit of COPI vesicle coatomer complex, which surrounds transport vesicles in the early secretory pathway; 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 (1201 aa)

ERV29
Protein localized to COPII-coated vesicles, involved in vesicle formation and incorporation of specific secretory cargo; Constituent of COPII-coated endoplasmic reticulum- derived transport vesicles. Required for efficient transport of a subset of secretory proteins to the Golgi. The C-terminal di- lysine motif is required for exit from the endoplasmic reticulum. Required directly for packaging glycosylated pro-alpha-factor into COPII vesicles. Facilitates retrograde transport from the Golgi to the endoplasmic reticulum (310 aa)
     
   
  0.729
ERV25
Protein that forms a heterotrimeric complex with Erp1, Erp2p, and Emp24, member of the p24 family involved in endoplasmic reticulum to Golgi transport; Constituent of COPII-coated endoplasmic reticulum- derived transport vesicles. Required for efficient transport of a subset of secretory proteins to the Golgi. Possesses a C-terminal dilysine motif that interacts with COPI coat subunits. Facilitates retrograde transport from the Golgi to the endoplasmic reticulum (211 aa)

ERP1
Protein that forms a heterotrimeric complex with Erp2p, Emp24p, and Erv25p; member, along with Emp24p and Erv25p, of the p24 family involved in ER to Golgi transport and localized to COPII-coated vesicles; Involved in vesicular protein trafficking (219 aa)

VMA21
Integral membrane protein that is required for vacuolar H+-ATPase (V-ATPase) function, although not an actual component of the V-ATPase complex; functions in the assembly of the V-ATPase; localized to the yeast endoplasmic reticulum (ER); Functions with VOA1 in assembly of the integral membrane sector (also called V0 sector) of the V-ATPase in the endoplasmic reticulum. Escorts the assembled V0 sector in COPII vesicles. Also required for normal packaging of the SNARE BOS1 and possibly the ER to Golgi transport receptor ERV29 (77 aa)

EMP24
Component of the p24 complex; binds to GPI anchor proteins and mediates their efficient transport from the ER to the Golgi; integral membrane protein that associates with endoplasmic reticulum-derived COPII-coated vesicles; Constituent of COPII-coated endoplasmic reticulum- derived transport vesicles.
