BUBR1 Kinase (also called Mitotic checkpoint serine/threonine-protein kinase, BUB1 beta, MAD3/BUB1-related protein kinase, Mitotic checkpoint kinase MAD3L and SSK1) is a probable component of the mitotic checkpoint that delays anaphase until all chromosomes are properly attached to the mitotic spindle. This protein can interact with BUB3, CENP-F, CENP-E and mitosin. BUBR1 Kinase is found within the cytoplasm in interphase cells, but when bound to BUB3 or CENP-E, it can be localized to nuclear kinetochores. This protein is highly expressed in thymus followed by spleen. Defects in BUB1B are associated with tumor formation.
This protein A purified monoclonal antibody was produced by repeated immunizations with a recombinant protein corresponding to amino acid residues 1-350 of human BUBR1 Kinase protein.
