STRINGSTRING
OSH7 protein (Saccharomyces cerevisiae) - STRING interaction network
"OSH7" - Member of an oxysterol-binding protein family with seven members in S. cerevisiae 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

OSH7Member of an oxysterol-binding protein family with seven members in S. cerevisiae; family members have overlapping, redundant functions in sterol metabolism and collectively perform a function essential for viability; Lipid transporter involved in lipid countertransport between the endoplasmic reticulum and the plasma membrane- specifically exchanges phosphatidylserine with phosphatidylinositol 4-phosphate (PI4P), delivering phosphatidylserine to the plasma membrane in exchange for PI4P, which is degraded by the SAC1 phosphatase in the endoplasmic reticulum. Binds phosphatidylserine an [...] (437 aa)    
Predicted Functional Partners:
MID2
O-glycosylated plasma membrane protein that acts as a sensor for cell wall integrity signaling and activates the pathway; interacts with Rom2p, a guanine nucleotide exchange factor for Rho1p, and with cell integrity pathway protein Zeo1p; Cell wall stress sensor. Involved in activation of a response that includes both stress-related increased chitin synthesis and the MPK1 mitogen-activated protein kinase cell integrity pathway. High-copy activator of the SKN7 transcription factor. Required during induction of MPK1 tyrosine phosphorylation under a variety of stress conditions. Required [...] (376 aa)
