YMR1

phosphatidylinositol-3-phosphatase YMR1, YJR110W
Phosphatidylinositol 3-phosphate (PI3P) phosphatase; involved in various protein sorting pathways, including CVT targeting and endosome to vacuole transport; has similarity to the conserved myotubularin dual specificity phosphatase family

INP52

SJL2, phosphatidylinositol-3-/phosphoinositide 5-phosphatase INP52, L000003985, YNL106C
Polyphosphatidylinositol phosphatase; dephosphorylates a number of phosphatidylinositol phosphates (PtdInsPs, PIPs) to PI; involved in endocytosis; hyperosmotic stress causes translocation to actin patches; synaptojanin-like protein with a Sac1 domain; INP52 has a paralog, INP53, 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.

PtdIns(3)P accumulation in triple lipid-phosphatase-deletion mutants triggers lethal hyperactivation of the Rho1p/Pkc1p cell-integrity MAP kinase pathway.

Parrish WR, Stefan CJ, Emr SD

In the budding yeast Saccharomyces cerevisiae, the regulation of phosphatidylinositol 3-phosphate [PtdIns(3)P] is an essential function shared by the myotubularin-related phosphatase Ymr1p and the synaptojanin-like phosphatases Sjl2p and Sjl3p. The aim of this study was to gain further insight into the mechanisms underlying the toxicity of PtdIns(3)P accumulation in ymr1Delta sjl2Delta sjl3Delta mutant cells. We conducted a genetic screen to ... [more]
