CC -!- FUNCTION: Serine/threonine-protein kinase component of the chromosomal
CC passenger complex (CPC), a complex that acts as a key regulator of
CC mitosis. The CPC complex has essential functions at the centromere in
CC ensuring correct chromosome alignment and segregation and is required
CC for chromatin-induced microtubule stabilization and spindle assembly.
CC Involved in the bipolar attachment of spindle microtubules to
CC kinetochores and is a key regulator for the onset of cytokinesis during
CC mitosis. Required for central/midzone spindle assembly and cleavage
CC furrow formation. Key component of the cytokinesis checkpoint, a
CC process required to delay abscission to prevent both premature
CC resolution of intercellular chromosome bridges and accumulation of DNA
CC damage. Phosphorylates 'Ser-10' of histone H3 during mitosis.
CC {ECO:0000250|UniProtKB:Q96GD4}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-

CC EC=2.7.11.1; Evidence={ECO:0000250|UniProtKB:Q96GD4};
CC -!- ACTIVITY REGULATION: Kinase activity is stimulated by cell-cycle
CC specific phosphorylation. {ECO:0000250|UniProtKB:Q96GD4}.
CC -!- SUBUNIT: Component of the chromosomal passenger complex (CPC).
CC {ECO:0000250|UniProtKB:Q96GD4}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q96GD4}.
CC Chromosome {ECO:0000250|UniProtKB:Q96GD4}. Chromosome, centromere
CC {ECO:0000250|UniProtKB:Q96GD4}. Cytoplasm, cytoskeleton, spindle
CC {ECO:0000250|UniProtKB:Q96GD4}. Midbody {ECO:0000250|UniProtKB:Q96GD4}.
CC Note=Localizes on chromosome arms and inner centromeres from prophase
CC through metaphase and then transferring to the spindle midzone and
CC midbody from anaphase through cytokinesis. Localization (and probably
CC targeting of the CPC) to the inner centromere occurs predominantly in
CC regions with overlapping mitosis-specific histone phosphorylations
CC H3pT3 and H2ApT12. {ECO:0000250|UniProtKB:Q96GD4}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC kinase family. Aurora subfamily. {ECO:0000255|PROSITE-
CC ProRule:PRU00159}.
