STRINGSTRING
FIG1 protein (Saccharomyces cerevisiae) - STRING interaction network
"FIG1" - Integral membrane protein required for efficient mating 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

FIG4
Phosphatidylinositol 3,5-bisphosphate (PtdIns[3,5]P) phosphatase; required for efficient mating and response to osmotic shock; physically associates with and regulated by Vac14p; contains a SAC1-like domain; The PI(3,5)P2 regulatory complex regulates both the synthesis and turnover of phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2). Major enzyme required for hyperosmotic shock- induced turnover of PtdIns(3,5)P2 and requires VAC14 for this function. In vivo, mediates turnover of PtdIns(3,5)P2 at the vacuole membrane necessary for vacuolar size control. In vitro, catalyzes the remo [...] (879 aa)

MID1
N-glycosylated integral membrane protein of the ER and plasma membrane; functions as a stretch-activated Ca2+-permeable cation channel required for Ca2+ influx stimulated by pheromone; interacts with Cch1p; forms an oligomer; Calcium-permeable, cation-selective stretch-activated channel (SAC). Required for calcium influx and for vitality of MATa cells in a late, pheromone-induced event of the mating process requiring calcium induced signaling. Functions together with CCH1 to ensure that adequate levels of Ca(2+) are supplied to PMR1 to sustain secretion and growth. Required for growth [...] (548 aa)
