VPS38

VPL17, L000003511, YLR360W
Part of a Vps34p phosphatidylinositol 3-kinase complex; functions in carboxypeptidase Y (CPY) sorting; binds Vps30p and Vps34p to promote production of phosphatidylinositol 3-phosphate (PtdIns3P) which stimulates kinase activity; required for overflow degradation of misfolded proteins when ERAD is saturated

Synthetic Rescue

A genetic interaction is inferred when mutations or deletions of one gene rescues the lethality or growth defect of a strain mutated or deleted for another gene.

The PI3 Kinase Complex II-PI3P-Vps27 Axis on Vacuolar Membranes is Critical for Microautophagy Induction and Nutrient Stress Adaptation.

Tasnin MN, Ito K, Katsuta H, Takuma T, Sharmin T, Ushimaru T

Phosphatidylinositol 3-phosphate (PI3P), a scaffold of membrane-associated proteins required for diverse cellular events, is produced by Vps34-containing phosphatidylinositol 3-kinase (PI3K). PI3K complex I (PI3KCI)-generated PI3P is required for macroautophagy, whereas PI3K complex II (PI3KCII)-generated PI3P is required for endosomal sorting complex required for transport (ESCRT)-mediated multi-vesicular body (MVB) formation in late endosomes. ESCRT also promotes vacuolar membrane remodeling in microautophagy ... [more]

Throughput

  • Low Throughput

Ontology Terms

  • phenotype: starvation resistance (APO:0000091)

Additional Notes

  • Artificial tethering of Vps27 to Pho8 largely suppressed the high lethality during starvation in vps38 deletion cells
