SEC14

PIT1, phosphatidylinositol/phosphatidylcholine transfer protein SEC14, L000001839, YMR079W
Phosphatidylinositol/phosphatidylcholine transfer protein; involved in regulating PtdIns, PtdCho, and ceramide metabolism, products of which regulate intracellular transport and UPR; has a role in localization of lipid raft proteins; functionally homologous to mammalian PITPs; SEC14 has a paralog, YKL091C, that arose from the whole genome duplication
Saccharomyces cerevisiae (S288c)
PREY

CKI1

bifunctional choline kinase/ethanolamine kinase CKI1, L000000346, YLR133W
Choline kinase; catalyzes the first step in phosphatidylcholine synthesis via the CDP-choline (Kennedy pathway); exhibits some ethanolamine kinase activity contributing to phosphatidylethanolamine synthesis via the CDP-ethanolamine pathway; CKI1 has a paralog, EKI1, that arose from the whole genome duplication

Phenotypic Enhancement

A genetic interaction is inferred when mutation or overexpression of one gene results in enhancement of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.

Publication

Regulation of phospholipid biosynthesis by phosphatidylinositol transfer protein Sec14p and its homologues. A critical role for phosphatidic acid.

Holic R, Zagorsek M, Griac P

Transcription of yeast phospholipid biosynthesis structural genes, which contain an inositol-sensitive upstream activating sequence in their promoters, responds to the availability of the soluble precursors inositol and choline and to changes in phospholipid metabolism. The INO1 gene is deregulated (derepressed when inositol is present) under the conditions of increased phosphatidylcholine (PtdCho) turnover, as occurs in the sec14Delta cki1Delta strain (SEC14 ...
