YLL010C
Plasma membrane associated protein phosphatase; involved in the general stress response; required along with binding partner Whi2p for full activation of STRE-mediated gene expression, possibly through dephosphorylation of Msn2p; PSR1 has a paralog, PSR2, 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

Yeast Whi2 and Psr1-phosphatase form a complex and regulate STRE-mediated gene expression.

Kaida D, Yashiroda H, Toh-e A, Kikuchi Y

BACKGROUND: In response to various stressful situations, including diauxic conditions, the Msn2 and Msn4 transcription factors induce STRE-mediated gene expression of many stress responsive genes in Saccharomyces cerevisiae. This is called the general stress response. The whi2 cells in the stationary phase are smaller than wild-type cells. RESULTS: Here we demonstrate that STRE-mediated gene expression in whi2 cells is reduced ... [more]

Synthetic Growth Defect

A genetic interaction is inferred when mutations in separate genes, each of which alone causes a minimal phenotype, result in a significant growth defect under a given condition when combined in the same cell.
