Aurora kinase B (AURKB)

Serine/threonine-protein kinase part of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. The CPC complex has essential functions in the centromere in ensuring proper chromosome alignment and segregation and is required for chromatin-induced microtubule stabilization and spindle assembly.

Involved in the bipolar attachment of spindle microtubules to kinetochores and is a key regulator for the onset of cytokinesis during mitosis. Required for central/midzone spindle assembly and cleavage furrow formation.
