CC -!- FUNCTION: Plays a key role in the control of the eukaryotic cell cycle
CC (By similarity). Required for entry into S-phase and mitosis (By
CC similarity). Acts as a component of the kinase complex that
CC phosphorylates the repetitive C-terminus of RNA polymerase II (By
CC similarity). May function in concert with npp-16 to arrest prophase
CC blastomeres in response to anoxia (By similarity).
CC {ECO:0000250|UniProtKB:P06493, ECO:0000250|UniProtKB:P34556}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-

CC Evidence={ECO:0000250|UniProtKB:P06493};
CC -!- ACTIVITY REGULATION: Phosphorylation both activates and inactivates the
CC enzyme depending on the site of phosphorylation.
CC {ECO:0000250|UniProtKB:P34556}.
CC -!- SUBUNIT: Forms a stable but non-covalent complex with a regulatory
CC subunit and with a cyclin. Interacts with cks-1 (By similarity).
CC {ECO:0000250|UniProtKB:P06493, ECO:0000250|UniProtKB:P34556}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:P39951}.
CC Cytoplasm, cytoskeleton, microtubule organizing center, centrosome
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr
CC protein kinase family. CDC2/CDKX subfamily. {ECO:0000255}.
