Trafficking (BBSome, small GTPases, vesicular transport, ATPases)

Function

BioID2-tagged BUB1, BUB3, BUBR1, MAD1L1, and MAD2L1 localized to kinetochores, overlapping fluorescence sig l with anticentromere antibodies (ACA) during prometaphase. BUB1 ki se activity was important for its proper localization to kinetochores and for the localization of the Astrin–Ki strin minor complex components PLK1 and SGO2 to the kinetochore ( 34087075). The Astrin–Ki strin complex is important for aligning and attaching to kinetochores(34087075).
