STRINGSTRING
MSS4 protein (Saccharomyces cerevisiae) - STRING interaction network
"MSS4" - Phosphatidylinositol-4-phosphate 5-kinase, involved in actin cytoskeleton organization and cell morphogenesis 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

MSS4Phosphatidylinositol-4-phosphate 5-kinase, involved in actin cytoskeleton organization and cell morphogenesis; multicopy suppressor of stt4 mutation; Catalyzes the phosphorylation of phosphatidylinositol 4- phosphate on the fifth hydroxyl of the myo-inositol ring, to form phosphatidylinositol 4,5-bisphosphate. Acts downstream of STT4, but in a pathway that does not involve PKC1. May be involved in the organization of the actin cytoskeleton (779 aa)    
Predicted Functional Partners:
STT4
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)
     
  0.993
PIK1
Phosphatidylinositol 4-kinase; catalyzes first step in the biosynthesis of phosphatidylinositol-4,5-biphosphate; may control cytokinesis through the actin cytoskeleton; Acts on phosphatidylinositol (PI) in the first committed step in the production of the second messenger inositol 1,4,5,- trisphosphate. PIK1 is part of a nuclear phosphoinositide cycle and could control cytokinesis through the actin cytoskeleton (1066 aa)
     
  0.991
PLC1
Phospholipase C, hydrolyzes phosphatidylinositol 4,5-biphosphate (PIP2) to generate the signaling molecules inositol 1,4,5-triphosphate (IP3) and 1,2-diacylglycerol (DAG); involved in regulating many cellular processes; The production of the second messenger molecules diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) is mediated by activated phosphatidylinositol-specific phospholipase C enzymes. Required for cell growth, osmoresistance and expression of GPD1 (869 aa)

INP52
Polyphosphatidylinositol phosphatase, dephosphorylates a number of phosphatidylinositols (PIs) to PI; involved in endocytosis; hyperosmotic stress causes translocation to actin patches; synaptojanin-like protein with a Sac1 domain; Dephosphorylates a number of phosphatidylinositols (PIs) like phosphatidylinositol 4,5-bisphosphate (PtdIns(4,5)P2), but also phosphatidylinositol 3-phosphate (PtdIns(3)P), phosphatidylinositol 4-phosphate (PtdIns(4)P), and phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2).

INP51
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).
