BUB2

PAC7, L000000197, YMR055C
Mitotic exit network regulator; forms GTPase-activating Bfa1p-Bub2p complex that binds Tem1p and spindle pole bodies, blocks cell cycle progression before anaphase in response to spindle and kinetochore damage

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.

The Bub2p spindle checkpoint links nuclear migration with mitotic exit.

Pereira G, Hoefken T, Grindlay J, Manson C, Schiebel E

Bfa1p and Bub2p are spindle checkpoint proteins that likely have GTPase activation activity and are associated with the budding yeast spindle pole body (SPB). Here, we show that Bfa1p and Bub2p bind the Ras-like GTPase Tem1p, a component of the mitotic exit network, to the cytoplasmic face of the SPB that enters the bud, whereas the GDP/GTP exchange factor Lte1p ...
