Whi5 phosphorylation by Cln3-Cdk1 embedded in the G1/S network dynamically controls critical cell size and cell fate.
Title: Whi5 phosphorylation embedded in the G1/S network dynamically controls critical cell size and cell fate.
at its most fundamental level, size control in budding yeast results from the differential scaling of Cln3 and Whi5 synthesis rates with cell size
Title: Dilution of the cell cycle inhibitor Whi5 controls budding-yeast cell size.
Hog1 interacts with and phosphorylates components of the core cell cycle transcriptional machinery such as Whi5 and the coregulator Msa1. Phosphorylation of these two transcriptional regulators by Hog1 is essential for inhibition of G1 cyclin expression.
Title: Hog1 targets Whi5 and Msa1 transcription factors to downregulate cyclin expression upon stress.
study describes a protein motif, the GTB motif (for G1/S transcription factor binding), in Nrm1 and Whi5 that is required to bind to the transcription factors
Title: Repression of G1/S transcription is mediated via interaction of the GTB motifs of Nrm1 and Whi5 with Swi6.
Cln3 regulates SBF by at least two different pathways, one involving the repressive protein Whi5, and the second involving Stb1.
Title: Recruitment of Cln3 cyclin to promoters controls cell cycle entry via histone deacetylase and other targets.
In a manner analogous to cyclin D/CDK4/6, which phosphorylates Rb in mammalian cells disrupting its association with HDACs, phosphorylation by the early G1 CDKs Cln3-Cdc28 and Pcl9-Pho85 inhibits association of Whi5 with the HDACs.
Title: Dual regulation by pairs of cyclin-dependent protein kinases and histone deacetylases controls G1 transcription in budding yeast.

Preferred Names: transcriptional repressor WHI5

NP_014726.1

Repressor of G1 transcription; binds to SCB binding factor (SBF) at SCB target promoters in early G1; WHI5 expression is repressed in M/early G phase; phosphorylation of Whi5p by G1 cyclin (Cln)/Cdc28p relieves repression and promoter binding by Whi5p, drives nuclear export, and contributes to both the determination of critical cell size at START and cell fate; dephosphorylated and re-imported into the nucleus post-START during the starvation response, reversing commitment
