CC -!- FUNCTION: Serine/threonine-protein kinase (By similarity). Involved in
CC the control of the cell cycle. Required for entry into S-phase and
CC mitosis (By similarity). Probable component of the kinase complex that
CC phosphorylates the repetitive C-terminus of RNA polymerase II (By
CC similarity). {ECO:0000250|UniProtKB:P04551,
CC ECO:0000250|UniProtKB:P61075}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-

CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:P61075};
CC -!- ACTIVITY REGULATION: Phosphorylation at Thr-14 or Tyr-15 inactivates
CC the enzyme, while phosphorylation at Thr-158 activates it.
CC {ECO:0000250|UniProtKB:P24941}.
CC -!- SUBUNIT: May form a complex composed of at least the catalytic subunit
CC CRK2 and a cyclin. {ECO:0000250|UniProtKB:P61075}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P04551}.
CC -!- DEVELOPMENTAL STAGE: Expressed at a low level during the asexual cell-
CC cycle within the host erythrocytes. Also expressed in gametocytes and
CC in stages during development in the mosquito.
CC {ECO:0000269|PubMed:9803415}.
CC -!- DISRUPTION PHENOTYPE: Normal asexual development in host erythrocytes,
CC normal ookinete and oocyte development in the mosquito vector, normal
CC number of oocyte and salivary gland sporozoites (PubMed:20951971).
CC Normal transmission into the mouse host (PubMed:20951971).
CC {ECO:0000269|PubMed:20951971}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr
CC protein kinase family. CDC2/CDKX subfamily. {ECO:0000305}.
