YMR1 protein (Saccharomyces cerevisiae) - STRING interaction network
"YMR1" - Phosphatidylinositol 3-phosphate in Saccharomyces cerevisiae
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 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
protein homology

Phosphatidylinositol 4,5-bisphosphate 5-phosphatase, synaptojanin-like protein with an N-terminal Sac1 domain, plays a role in phosphatidylinositol 4,5-bisphosphate homeostasis and in endocytosis; null mutation confers cold-tolerant growth; Controls the cellular levels and subcellular distribution of phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2). Does not utilize phosphatidylinositol 3,5- bisphosphate (PtdIns(3,5)P2), nor phosphatidylinositol 3-phosphate (PtdIns(3)P) and phosphatidylinositol 4-phosphate (PtdIns(4)P). Plays an essential role in a TGN (trans Golgi network)-to-ear [...] (946 aa)
Phosphatidylinositol 4,5-bisphosphate 5-phosphatase; role in secretion; localizes to the endoplasmic reticulum via the C-terminal tail; lacks the Sac1 domain and proline-rich region found in the other 3 INP proteins; Regulates the phosphatidylinositol (4,5)-diphosphate levels on the cytoplasmic surface of the endoplasmic reticulum and thereby regulates secretion. Does not utilize phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2), nor phosphatidylinositol 3- phosphate (PtdIns(3)P) and phosphatidylinositol 4-phosphate (PtdIns(4)P) (384 aa)
Phosphatidylinositol phosphate (PtdInsP) phosphatase involved in hydrolysis of PtdIns[4]P; transmembrane protein localizes to ER and Golgi; involved in protein trafficking and processing, secretion, and cell wall maintenance; Phosphoinositide phosphatase that hydrolyzes PtdIns(3)P and PtdIns(4)P. Has low activity towards PtdIns(3,5)P2. May be involved in the coordination of the activities of the secretory pathway and the actin cytoskeleton (623 aa)
Phosphatidylinositol-4-kinase; functions in the Pkc1p protein kinase pathway; required for normal vacuole morphology, cell wall integrity, and actin cytoskeleton organization; Acts on phosphatidylinositol (PI) in the first committed step in the production of the second messenger inositol 1,4,5,- trisphosphate. STT4 functions in PKC1 protein kinase pathway (1900 aa)
Phosphatidylinositol 3-kinase responsible for the synthesis of phosphatidylinositol 3-phosphate; forms membrane-associated signal transduction complex with Vps15p to regulate protein sorting; activated by the GTP-bound form of Gpa1p; Phosphatidylinositol 3-kinase required for cytoplasm to vacuole transport (Cvt) and autophagy as a part of the autophagy- specific VPS34 PI3-kinase complex I. This complex is essential to recruit the ATG8-phosphatidylinositol conjugate and the ATG12-ATG5 conjugate to the pre-autophagosomal structure. Also involved in endosome-to-Golgi retrograde transport [...] (875 aa)
Nexin-1 homolog required for localizing membrane proteins from a prevacuolar/late endosomal compartment back to the late Golgi apparatus; structural component of the retromer membrane coat complex; forms a retromer subcomplex with Vps17p; Plays a role in vesicular protein sorting.
