STRINGSTRING
GCS1 protein (Saccharomyces cerevisiae) - STRING interaction network
"GCS1" - ADP-ribosylation factor GTPase activating protein (ARF GAP), involved in ER-Golgi transport 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

GCS1ADP-ribosylation factor GTPase activating protein (ARF GAP), involved in ER-Golgi transport; shares functional similarity with Glo3p; GTPase-activating protein (GAP) for ARF1 and ARF2. Involved in intracellular vesicular transport. Required for transport from the trans-Golgi network. Implicated in the regulation of retrograde transport from the Golgi to the ER and in actin cytoskeletal organization. May be involved in the maintenance of mitochondrial morphology, possibly through organizing the actin cytoskeleton in Saccharomyces (352 aa)    
Predicted Functional Partners:
ARF2
ADP-ribosylation factor, GTPase of the Ras superfamily involved in regulation of coated formation vesicles in intracellular trafficking within the Golgi; functionally interchangeable with Arf1p; GTP-binding protein involved in protein trafficking; may modulate vesicle budding and uncoating within the Golgi apparatus (181 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)

ERD2
HDEL receptor, an integral membrane protein that binds to the HDEL motif in proteins destined for retention in the endoplasmic reticulum; has a role in maintenance of normal levels of ER-resident proteins; Required for the retention of luminal endoplasmic reticulum proteins. Determines the specificity of the luminal ER protein retention system. Also required for normal vesicular traffic through the Golgi. This receptor strongly recognizes H-D- E-L and weakly recognizes D-D-E-L and K-D-E-L (219 aa)
