Gene Ontology Information

Protein Name	Whi5p
Description	Repressor of G1 transcription; binds to SCB binding factor (SBF) at SCB target promoters in early G1; dilution of Whi5p concentration during cell growth determines cell size; phosphorylation of Whi5p by the CDK, Cln3p/Cdc28p relieves repression and promoter binding by Whi5, and contributes to both the determination of critical cell size at START and cell fate; periodically expressed in G1
GO Terms: Biological Process	level 3: cell cycle level 6: negative regulation of transcription involved in G1/S transition of mitotic cell cycle level 6: regulation of cell size level 7: DNA-templated transcription elongation level 10: traversing start control point of mitotic cell cycle
GO Terms: Molecular Function	level 3: transcription coregulator activity level 4: transcription corepressor activity level 6: RNA polymerase II-specific DNA-binding transcription factor binding
GO Terms: Cellular Component	level 3: cytoplasm level 5: SBF transcription complex level 5: nucleus
