SIT4

PPH1, type 2A-related serine/threonine-protein phosphatase SIT4, L000001901, YDL047W
Type 2A-related serine-threonine phosphatase; functions in the G1/S transition of the mitotic cycle; regulator of COPII coat dephosphorylation; required for ER to Golgi traffic; interacts with Hrr25p kinase; cytoplasmic and nuclear protein that modulates functions mediated by Pkc1p including cell wall and actin cytoskeleton organization; similar to human PP6

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.

A suppressor of a HIS4 transcriptional defect encodes a protein with homology to the catalytic subunit of protein phosphatases.

Arndt KT, Styles CA, Fink GR

Reversion analysis has identified four suppressor genes that permit transcription of the Saccharomyces cerevisiae HIS4 gene in the absence of GCN4, BAS1, and BAS2, trans-acting proteins normally required for activation of HIS4 transcription. These suppressor genes encode factors that affect the transcription of many diverse genes. Two of these suppressors, SIT1 and SIT2, are encoded by RPB1 and RPB2, the ... [more]
