Facts about Mitotic checkpoint serine/threonine-protein kinase BUB1 beta.
One of its checkpoint functions would be to inhibit the action of the anaphase-promoting complex/cyclosome (APC/C) by blocking the binding of CDC20 into APC/C, independently of its kinase activity. The other is to monitor kinetochore activities that depend on the kinetochore motor CENPE.

Highly expressed in thymus followed by spleen. Preferentially expressed in tissues with a high mitotic index.
Cytoplasm. Nucleus. Chromosome, centromere, kinetochore. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Cytoplasmic in interphase cells. Associates with the kinetochores in early prophase. Kinetochore localization requires BUB1, PLK1 and KNL1.
