CLN2

cyclin CLN2, L000000358, YPL256C
G1 cyclin involved in regulation of the cell cycle; activates Cdc28p kinase to promote the G1 to S phase transition; late G1 specific expression depends on transcription factor complexes, MBF (Swi6p-Mbp1p) and SBF (Swi6p-Swi4p); CLN2 has a paralog, CLN1, that arose from the whole genome duplication

BUD2

CLA2, ERC25, L000000199, YKL092C
GTPase activating factor for Rsr1p/Bud1p; plays a role in spindle position checkpoint distinct from its role in bud site selection; required for both axial and bipolar budding patterns; mutants exhibit random budding in all cell types

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

Publication

Yeast G1 cyclins CLN1 and CLN2 and a GAP-like protein have a role in bud formation.

Cvrckova F, Nasmyth K

Cyclin-dependent protein kinases have a central role in cell cycle regulation. In Saccharomyces cerevisiae, Cdc28 kinase and the G1 cyclins Cln1, 2 and 3 are required for DNA replication, duplication of the spindle pole body and bud emergence. These three independent processes occur simultaneously in late G1 when the cells reach a critical size, an event known as Start. At ... [more]
