TAF4 | TFIID subunit (48 kDa); involved in RNA polymerase II transcription initiation; potential Cdc28p substrate. (388 aa) | ||||
WHI5 | G1-specific transcriptional repressor WHI5; 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; Belongs to the WHI5/NRM1 family. (295 aa) |
