PIK120, PIK41, 1-phosphatidylinositol 4-kinase, L000001439, L000001438, YNL267W
Phosphatidylinositol 4-kinase; catalyzes first step in the biosynthesis of phosphatidylinositol-4,5-biphosphate; may control cytokinesis through the actin cytoskeleton; may control nonselective autophagy and mitophagy through trafficking of Atg9p

Polyphosphatidylinositol phosphatase; dephosphorylates multiple phosphatidylinositol phosphates; involved in trans Golgi network-to-early endosome pathway; hyperosmotic stress causes translocation to actin patches; contains Sac1 and 5-ptase domains; INP53 has a paralog, INP52, that arose from the whole genome duplication

Synthetic Lethality
A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Interaction of Pik1p and Sjl proteins in membrane trafficking.
Phosphatidylinositol (PtdIns) phosphates are involved in signal transduction, cytoskeletal organization, and membrane traffic. PtdIns 4-phosphate [PtdIns(4)P], produced in yeast by PtdIns 4-kinase (Pik1p), appears to regulate Golgi secretory function. PtdIns(4)P is also produced by dephosphorylation of phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2], catalyzed by one of the three yeast Sjl proteins, homologs of the mammalian synaptic vesicle-associated PtdIns(4,5)P2 5-phosphatase, synaptojanin. To determine whether ... [more]
