PSR1

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

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.

The Whi2-Psr1-Psr2 complex selectively regulates TORC1 and autophagy under low leucine conditions but not nitrogen depletion.

Amino acids and ammonia serve as sources of nitrogen for cell growth and were previously thought to have similar effects on yeast. Consistent with this idea, depletion of either of these two nitrogen sources inhibits the target of rapamycin complex 1 (TORC1), leading to induction of macroautophagy/autophagy and inhibition of cell growth. In this study, we show that Whi2 and ... [more]
