DAF1, FUN10, WHI1, cyclin CLN3, L000000359, YAL040C
G1 cyclin involved in cell cycle progression; activates Cdc28p kinase to promote the G1 to S phase transition; plays a role in regulating transcription of the other G1 cyclins, CLN1 and CLN2; regulated by phosphorylation and proteolysis; acetly-CoA induces CLN3 transcription in response to nutrient repletion to promote cell-cycle entry.
Saccharomyces cerevisiae (S288c)


transcription factor MBP1, L000001032, YDL056W
Transcription factor; involved in regulation of cell cycle progression from G1 to S phase, forms a complex with Swi6p that binds to MluI cell cycle box regulatory element in promoters of DNA synthesis genes
Saccharomyces cerevisiae (S288c)

Phenotypic Suppression

A genetic interaction is inferred when mutation or over expression of one gene results in suppression of any phenotype (other than lethality/growth defect) associated with mutation or over expression of another gene.


Genetic analysis of the shared role of CLN3 and BCK2 at the G(1)-S transition in Saccharomyces cerevisiae.

Wijnen H, Futcher B

The transcription complexes SBF and MBF mediate the G(1)-S transition in the cell cycle of Saccharomyces cerevisiae. In late G(1), SBF and MBF induce a burst of transcription in a number of genes, including G(1)- and S-phase cyclins. Activation of SBF and MBF depends on the G(1) cyclin Cln3 and a largely uncharacterized protein called Bck2. We show here that ... [more]
