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

Dosage Lethality
A genetic interaction is inferred when over expression or increased dosage of one gene causes lethality in a strain that is mutated or deleted for another gene.

Role of a ubiquitin-conjugating enzyme in degradation of S- and M-phase cyclins.
Cell cycle progression in eukaryotes is controlled by the p34cdc2/CDC28 protein kinase and its short-lived, phase-specific regulatory subunits called cyclins. In Xenopus oocytes, degradation of M-phase (B-type) cyclins is required for exit from mitosis and is mediated by the ubiquitin-dependent proteolytic system. Here we show that B-type-cyclin degradation in yeast involves an essential nuclear ubiquitin-conjugating enzyme, UBC9. Repression of UBC9 ... [more]
