CLB5

B-type cyclin CLB5, L000000353, YPR120C
B-type cyclin involved in DNA replication during S phase; activates Cdc28p to promote initiation of DNA synthesis; functions in formation of mitotic spindles along with Clb3p and Clb4p; most abundant during late G1 phase; CLB5 has a paralog, CLB6, that arose from the whole genome duplication

DBF4

DNA52, LSD7, protein serine/threonine kinase activating protein DBF4, L000000488, S000029149, L000000513, YDR052C
Regulatory subunit of Cdc7p-Dbf4p kinase complex; required for Cdc7p kinase activity and initiation of DNA replication; phosphorylates the Mcm2-7 family of proteins; cell cycle regulated; relative distribution to the nucleus increases upon DNA replication stress

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.

Limiting replication initiation factors execute the temporal programme of origin firing in budding yeast.

Mantiero D, Mackenzie A, Donaldson A, Zegerman P

Eukaryotic chromosomes are replicated from multiple origins that initiate throughout the S-phase of the cell cycle. Why all origins do not fire simultaneously at the beginning of S-phase is not known, but two kinase activities, cyclin-dependent kinase (CDK) and Dbf4-dependent kinase (DDK), are continually required throughout the S-phase for all replication initiation events. Here, we show that the two CDK ... [more]
