What's a GeneRIF?

PSK1 coordinates glucose metabolism and utilization and regulates energy-metabolism oscillation in Saccharomyces cerevisiae.
Title: PSK1 coordinates glucose metabolism and utilization and regulates energy-metabolism oscillation in Saccharomyces cerevisiae.
Snf1 phosphorylates and activates Psk1. Once activated, Psk1 may phosphorylate Pbp1, which is known to stimulate stress granule formation and inhibit TORC1 through sequestration. Thus, Psk1 is a link between energy status and cell growth/proliferation.
Title: PAS kinase is activated by direct SNF1-dependent phosphorylation and mediates inhibition of TORC1 through the phosphorylation and activation of Pbp1.
PSK1 mediated in vivo phosphorylation of Cbf1 at T211/T212 inhibits yeast cell respiration.
Title: A comprehensive protein-protein interactome for yeast PAS kinase 1 reveals direct inhibition of respiration through the phosphorylation of Cbf1.
Showed deletion of PSK1 increased sensitivity of yeast to ox. stress&partly inhibited cell growth; but the PSK2-deleted mutant was similar to that of the wild type. SOD1 mRNA and protein levels were lower in PSK1-deletion mutant than the wild type.
Title: PSK1 regulates expression of SOD1 involved in oxidative stress tolerance in yeast.
PAS kinases PSK1 and PSK2 coordinate glucose partitioning in response to metabolic and cell integrity signaling
Title: Yeast PAS kinase coordinates glucose partitioning in response to metabolic and cell integrity signaling.
Yeast PAS kinases phosphorylate UDP-glucose pyrophosphorylase, the primary producer of UDP-glucose and the glucose donor for glucan biosynthesis.
Title: Regulation of glucose partitioning by PAS kinase and Ugp1 phosphorylation.
