SCS2

phosphatidylinositol-binding protein SCS2, L000002629, YER120W
Integral ER membrane protein, regulates phospholipid metabolism; one of 6 proteins (Ist2p, Scs2p, Scs22p, Tcb1p, Tcb2p, Tcb3p) that connect ER to the plasma membrane (PM) and regulate PI4P levels by controlling access of Sac1p phosphatase to its substrate PI4P in the PM; interacts with FFAT motif of Opi1p; involved in telomeric silencing; null shows inositol auxotrophy above 34 deg C; VAP homolog; SCS2 has a paralog, SCS22, that arose from the whole genome duplication

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.

Suppressors of the Ca(2+)-sensitive yeast mutant (csg2) identify genes involved in sphingolipid biosynthesis. Cloning and characterization of SCS1, a gene required for serine palmitoyltransferase activity.

Zhao C, Beeler T, Dunn T

Suppressor mutations in Saccharomyces cerevisiae that block Ca(2+)-induced death of csg2 mutant cells were investigated. These mutants, called scs mutants (suppressor of Ca2+ sensitivity), fall into seven complementation groups (scs1-scs7). All mutant strains in two of the complementation groups (scs1 and scs2) simultaneously acquire a requirement for 10 mM Ca2+, whereas wild type grow with only trace amounts of Ca2+. ... [more]
