STRINGSTRING
SFH5 protein (Saccharomyces cerevisiae) - STRING interaction network
"SFH5" - Non-classical phosphatidylinositol transfer protein 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

SFH5Non-classical phosphatidylinositol transfer protein (PITP); exhibits PI- but not PC-transfer activity; localizes to the peripheral endoplasmic reticulum, cytosol and microsomes; similar to Sec14p; Non-classical phosphatidylinositol (PtdIns) transfer protein (PITP), which exhibits PtdIns-binding/transfer activity in the absence of detectable PtdCho-binding/transfer activity. Regulates PtdIns(4,5)P2 homeostasis at the plasma membrane (294 aa)    
Predicted Functional Partners:
