YGR188C / BUB1

Description: Protein kinase involved in the cell cycle checkpoint into anaphase; forms complex with Mad1p and Bub3p crucial to preventing cell cycle progression into anaphase in the presence of spindle damage; CDC28-mediated phosphorylation at Bub1p-T566 is important for its degradation in anaphase and adaptation of the checkpoint to prolonged mitotic arrest, but not to its kinase activity or chromosome segregation function; associates with centromere DNA via Skp1p
