SAC1

RSD1, phosphatidylinositol-3-phosphatase SAC1, L000001790, YKL212W
Phosphatidylinositol phosphate (PtdInsP) phosphatase; involved in hydrolysis of PtdIns[4]P in the early and medial Golgi; regulated by interaction with Vps74p; ER localized transmembrane protein which cycles through the Golgi; involved in protein trafficking and processing, secretion, and cell wall maintenance; regulates sphingolipid biosynthesis through the modulation of PtdIns(4)P metabolism
Saccharomyces cerevisiae (S288c)
PREY

MBR1

L000001033, YKL093W
Protein involved in mitochondrial functions and stress response; overexpression suppresses growth defects of hap2, hap3, and hap4 mutants; MBR1 has a paralog, ISF1, that arose from the whole genome duplication

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.

Publication

The MBR1 gene from Saccharomyces cerevisiae is activated by and required for growth under sub-optimal conditions.

Reisdorf P, Boy-Marcotte E, Bolotin-Fukuhara M

The MBR1 gene was isolated as a multicopy suppressor of the phenotype on glycerol medium of a Saccharomyces cerevisiae strain mutant for the Hap2/3/4/5 transactivator complex. In this paper, we show that Mbr1p is a limiting factor for growth on glycerol medium under the following sub-optimal culture conditions: in late growth phase, at low temperature, at high external pH or ...
