Coordinates Chr VII:875109..872044
Primary SGDID S000003420


Description of YGR188C: 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[1][2][3][4][5]
