SEC8

L000001834, YPR055W
Essential 121 kDa subunit of the exocyst complex; the exocyst mediates polarized targeting and tethering of post-Golgi secretory vesicles to active sites of exocytosis at the plasma membrane prior to SNARE-mediated fusion; involved in ER and Golgi inheritance in small buds; relocalizes away from bud neck upon DNA replication stress
Saccharomyces cerevisiae (S288c)

MSS4

1-phosphatidylinositol-4-phosphate 5-kinase, L000001203, YDR208W
Phosphatidylinositol-4-phosphate 5-kinase; involved in actin cytoskeleton organization and cell morphogenesis; multicopy suppressor of stt4 mutation

Dosage Rescue

A genetic interaction is inferred when over expression or increased dosage of one gene rescues the lethality or growth defect of a strain that is mutated or deleted for another gene.

Nonclassical PITPs activate PLD via the Stt4p PtdIns-4-kinase and modulate function of late stages of exocytosis in vegetative yeast.

Phospholipase D (PLD) is a PtdCho-hydrolyzing enzyme that plays central signaling functions in eukaryotic cells. We previously demonstrated that action of a set of four nonclassical and membrane-associated Sec14p-like phosphatidylinositol transfer proteins (PITPs) is required for optimal activation of yeast PLD in vegetative cells. Herein, we focus on mechanisms of Sfh2p and Sfh5p function in this regulatory circuit. We describe ... [more]

Synthetic Lethality
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.
