Component of the chromosomal passenger complex (CPC), a complex that acts as a key regulator of mitosis. The CPC complex has essential functions at the centromere in ensuring correct chromosome alignment and segregation and is required for chromatin-induced microtubule stabilization and spindle assembly. Acts as a scaffold regulating CPC localization and activity. The C-terminus associates with AURKB, the N-terminus associated with BIRC5/survivin and CDCA8/borealin tethers the CPC to the inner centromere, and the microtubule binding activity within the central SAH domain directs AURKB toward substrates near microtubules. The flexibility of the SAH domain is proposed to allow AURKB to follow substrates on dynamic microtubules while ensuring CPC docking to static chromatin. Activates AURKB.By similarity1 Publication

Caution

Originally predicted to contain a coiled coil domain but shown to contain a stable SAH domain instead.1 Publication
