CC -!- FUNCTION: Plays a key role in the control of the eukaryotic cell cycle
CC by modulating the centrosome cycle as well as mitotic onset; promotes
CC G2-M transition, and regulates G1 progress and G1-S transition via
CC association with multiple interphase cyclins. Required in higher cells
CC for entry into S-phase and mitosis. May play a role in regulating the
CC amplitude of the cyclic expression of circadian clock genes.
CC {ECO:0000250|UniProtKB:P06493}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-

CC Evidence={ECO:0000250|UniProtKB:P11440};
CC -!- ACTIVITY REGULATION: Phosphorylation at Thr-14 or Tyr-15 inactivates
CC the enzyme, while phosphorylation at Thr-161 activates it.
CC {ECO:0000250|UniProtKB:P06493}.
CC -!- SUBUNIT: Forms a stable but non-covalent complex with a regulatory
CC subunit and with a cyclin. {ECO:0000250|UniProtKB:P06493}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P06493}.
CC Cytoplasm, cytoskeleton, microtubule organizing center, centrosome
CC {ECO:0000250|UniProtKB:P06493}.
CC -!- PTM: Phosphorylation at Tyr-15 by wee1 and wee2 inhibits the protein
CC kinase activity and acts negative regulator of entry into mitosis (G2
CC to M transition). {ECO:0000250|UniProtKB:P06493}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr
CC protein kinase family. CDC2/CDKX subfamily. {ECO:0000305}.
