Bub3 - BUB3 mitotic checkpoint protein

Predicted to enable ubiquitin binding activity. Predicted to be involved in attachment of spindle microtubules to kinetochore; mitotic spindle assembly checkpoint signaling; and protein localization to kinetochore. Predicted to act upstream of or within mitotic sister chromatid segregation. Predicted to be located in nucleoplasm. Predicted to be part of bub1-bub3 complex and mitotic checkpoint complex. Predicted to be active in kinetochore. Orthologous to human BUB3 (BUB3 mitotic checkpoint protein). [provided by Alliance of Genome Resources, Apr 2022]
