Monoclonal Mouse Affinity Purified E B IP IC
Chromosome segregation and mitotic checkpoints are regulated by various proteins among them are BUB1 and BUBR1/BUB1B (Budding Uninhibited by Benzimidazoles 1). During mitosis both BUB1 and BUBR1 proteins are localized to kinetochores and inhibit the anaphase stage until all chromosomes are correctly attached to the spindle. These proteins were found due to their homology to Bub1 protein from yeast. Human BUBR1 contains CD1 and CD2 domains that are found in human, mouse and yeast BUB1 (3-5). The human and mouse BUBR1 proteins are 29% identical in these
regions. The kinetochore localization and Bub3 binding is found in the CD1 region while the kinase domain is found in the CD2 domain. While both human and mouse BUB1 contain a nuclear localization site between CD1 and CD2 regions, the yeast protein does not contain this site. BUB1 is expressed in many tissues with the highest expression in testis and thymus, lower expression in colon and small intestine and very low expression in spleen and ovary. BUB1 expression is in correlation with the expression of MAD2, another human spindle assembly checkpoint protein (3-5). BUBR1 is mainly expressed in testis, thymus and bone marrow while in differentiated tissues such as brain, heart and
muscle the expression is low (5).
