STRINGSTRING
PIK1 protein (Saccharomyces cerevisiae) - STRING interaction network
"PIK1" - Phosphatidylinositol 4-kinase 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

PIK1Phosphatidylinositol 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)    
Predicted Functional Partners:
FRQ1
N-myristoylated calcium-binding protein that may have a role in intracellular signaling through its regulation of the phosphatidylinositol 4-kinase Pik1p; member of the recoverin/frequenin branch of the EF-hand superfamily; Regulator of phosphatidylinositol 4-kinase PIK1 (190 aa)

MSS4
Phosphatidylinositol-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)

INP53
Polyphosphatidylinositol phosphatase, dephosphorylates multiple phosphatidylinositols; involved in trans Golgi network-to-early endosome pathway; hyperosmotic stress causes translocation to actin patches; contains Sac1 and 5-ptase domains; 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). Controls the cellular levels and subcellular distribution of phosphatidyl [...] (1107 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).

YPT32
Rab family GTPase, very similar to Ypt31p; involved in the exocytic pathway; mediates intra-Golgi traffic or the budding of post-Golgi vesicles from the trans-Golgi; Required for protein transport through the secretory pathway. Probably involved in regulation of secretory vesicle formation at the trans-Golgi compartment. Mediates the proper polarized localization of SEC2, a GEF for SEC4, but does not alter the exchange activity of SEC2 on SEC4. Plays a role in autophagy (222 aa)

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). Plays an essential role in a TGN (trans Golgi network)-to-ear [...] (946 aa)
