Mitotic checkpoint serine/threonine-protein kinase BUB1 beta is an enzyme that in humans is encoded by the BUB1B gene.[5]

Function

This gene encodes a kinase involved in spindle checkpoint function and chromosome segregation.[6] The protein has been localized to the kinetochore and plays a role in the inhibition of the anaphase-promoting complex/cyclosome (APC/C), delaying the onset of anaphase and ensuring proper chromosome segregation. Impaired spindle checkpoint function has been found in many forms of cancer.[7]

Increased expression of BubR1 in mice extends a healthy lifespan.[8]

Interactions

BUB1B has been shown to interact with:
