CC -!- FUNCTION: Required for high-fidelity chromosome segregation during the
CC later part of each cell cycle. Acts in opposition to the phosphatase
CC PP1. Has a role in attaching the kinetochores to the microtubules and
CC ensuring that sister kinetochores connect to opposite poles. The
CC promotion of bi-orientation is achieved by selectively detaching
CC kinetochore-microtubule attachments that are not under tension.
CC Phosphorylates histone H3 to form H3S10ph during mitosis and meiosis
CC (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-
CC [protein]; Xref=Rhea:RHEA:17989, Rhea:RHEA-COMP:9863, Rhea:RHEA-

CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm, cytoskeleton,
CC spindle {ECO:0000250}. Chromosome, centromere, kinetochore
CC {ECO:0000250}. Note=Associates with the mitotic spindle and on
CC elongated and disassembling spindles. Also associated with the
CC kinetochore (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. Ser/Thr protein
CC kinase family. Aurora subfamily. {ECO:0000255|PROSITE-
CC ProRule:PRU00159}.
