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
Saccharomyces cerevisiae (S288c)
PREY

INO1

APR1, inositol-3-phosphate synthase INO1, L000000867, YJL153C
Inositol-3-phosphate synthase; involved in synthesis of inositol phosphates and inositol-containing phospholipids; transcription is coregulated with other phospholipid biosynthetic genes by Ino2p and Ino4p, which bind the UASINO DNA element

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.

Publication

The Saccharomyces cerevisiae SCS2 gene product, a homolog of a synaptobrevin-associated protein, is an integral membrane protein of the endoplasmic reticulum and is required for inositol metabolism.

The Saccharomyces cerevisiae SCS2 gene has been cloned as a suppressor of inositol auxotrophy of CSE1 and hac1/ire15 mutants (J. Nikawa, A. Murakami, E. Esumi, and K. Hosaka, J. Biochem. 118:39-45, 1995) and has homology with a synaptobrevin/VAMP-associated protein, VAP-33, cloned from Aplysia californica (P. A. Skehel, K. C. Martin, E. R. Kandel, and D. Bartsch, Science 269:1580-1583, 1995). In ... [more]
