STRINGSTRING
SHR3 protein (Saccharomyces cerevisiae) - STRING interaction network
"SHR3" - Endoplasmic reticulum packaging chaperone, required for incorporation of amino acid permeases into COPII coated vesicles for transport to the cell surface 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

SHR3Endoplasmic reticulum packaging chaperone, required for incorporation of amino acid permeases into COPII coated vesicles for transport to the cell surface; Involved in amino acid permease processing and required for the efficient translocation of structurally related amino acid permeases from the endoplasmic reticulum to the plasma membrane. SHR3 may function as a permease-specific "adaptor" molecule that functions in conjunction with the SEC62/SEC63 complex. Yeast cells may require SHR3 to expedite the processing of permeases to ensure their rapid expression at the plasma membrane in [...] (210 aa)    
Predicted Functional Partners:
GAP1
General amino acid permease; Gap1p senses the presence of amino acid substrates to regulate localization to the plasma membrane when needed; Permease for various amino acids as well as for GABA. Can also transport L-cysteine and beta-alanine (602 aa)

HIP1
High-affinity histidine permease, also involved in the transport of manganese ions; High-affinity permease for histidine (603 aa)

SEC12
Guanine nucleotide exchange factor (GEF), activates Sar1p by catalyzing the exchange of GDP for GTP; required for the initiation of COPII vesicle formation in ER to Golgi transport; glycosylated integral membrane protein of the ER; Guanine nucleotide-exchange factor (GEF) required for the formation or budding of transport vesicles from the ER. This function involves the cytoplasmic domain of the protein, which is thought to interact with the small GTP-binding protein SAR1. Required for autophagy (471 aa)

SEC13
Component of the Nup84 nuclear pore sub-complex, the Sec13p-Sec31p complex of the COPII vesicle coat, and the SEA (Seh1-associated) complex; required for vesicle formation in ER to Golgi transport and nuclear pore complex organization; the Nup84 sub /.../x has a role in transcription elongation; Functions as a component of the nuclear pore complex (NPC) and the COPII coat. It is one of 5 proteins constituting the COPII coat, which is involved in anterograde (ER to Golgi) double- membrane transport vesicle formation.
