What's a GeneRIF?

The InsP7 phosphatase Siw14 regulates inositol pyrophosphate levels to control localization of the general stress response transcription factor Msn2.
Title: The InsP(7) phosphatase Siw14 regulates inositol pyrophosphate levels to control localization of the general stress response transcription factor Msn2.
three structural elements that demarcate a 9.2-A-deep substrate-binding pocket each have spatial equivalents in PTPs, but we identify how these are specialized for Siw14 to bind and hydrolyze the intensely negatively charged PP-InsPs
Title: Structural and biochemical characterization of Siw14: A protein-tyrosine phosphatase fold that metabolizes inositol pyrophosphates.
Siw14 is a novel inositol pyrophosphate phosphatase in Saccharomyces cerevisiae.
Title: A Novel Inositol Pyrophosphate Phosphatase in Saccharomyces cerevisiae: Siw14 PROTEIN SELECTIVELY CLEAVES THE β-PHOSPHATE FROM 5-DIPHOSPHOINOSITOL PENTAKISPHOSPHATE (5PP-IP5).
we conclude that Siw14 functions upstream of Pph21 and Pph22 as an inhibitor of the phosphorylation and localization of Gln3, and that Sit4 acts independently of Siw14
Title: The protein phosphatase Siw14 controls caffeine-induced nuclear localization and phosphorylation of Gln3 via the type 2A protein phosphatases Pph21 and Pph22 in Saccharomyces cerevisiae.
Siw14 controls the intracellular localization of Gln3 in combination with Npr1, and one of the causes for the caffeine sensitivity of the Deltasiw14 disruptant was an accumulation of dephosphorylated Gln3 in the nucleus.
Title: Protein phosphatase Siw14 controls intracellular localization of Gln3 in cooperation with Npr1 kinase in Saccharomyces cerevisiae.
