CC -!- FUNCTION: Protein kinase which plays an important role in mitotic cell
CC cycle progression. Required for chromosome segregation at metaphase-
CC anaphase transition, robust mitotic spindle formation and cytokinesis.
CC Phosphorylates ATF4, CIR1, PTN, RAD26L, RBBP6, RPS7, TRIP4, STAT3 and
CC histones H1 and H3. Phosphorylates KIF11 to promote mitotic spindle
CC formation. Involved in G2/M phase cell cycle arrest induced by DNA
CC damage. Inhibition of activity results in apoptosis. May contribute to
CC tumorigenesis by suppressing p53/TP53-induced cancer cell senescence
CC (By similarity). Phosphorylates RPS6KB1 (PubMed:11516946).
CC Phosphorylates EML4 at 'Ser-144', promoting its dissociation from
CC microtubules during mitosis which is required for efficient chromosome
CC congression (By similarity). {ECO:0000250|UniProtKB:Q9HC98,
CC ECO:0000269|PubMed:11516946}.

CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC -!- ACTIVITY REGULATION: Binding to NEK9 stimulates its activity by
CC releasing the autoinhibitory function of Tyr-108. {ECO:0000250}.
CC -!- SUBUNIT: Interacts with NEK9, predominantly in mitosis. Interacts with
CC KIF11 (via C-terminus). Interacts with APBB1 (via WW domain). Interacts
CC with ANKRA2, ATF4, ARHGAP33, CDC42, CIR1, PRAM1, PTN, PRDX3, PIN1,
CC RAD26L, RBBP6, RPS7, STAT3 and TRIP4 (By similarity). Interacts with
CC RPS6KB1. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC Nucleus speckle {ECO:0000250}. Cytoplasm, cytoskeleton, microtubule
CC organizing center, centrosome {ECO:0000250}. Cytoplasm, cytoskeleton,
CC spindle pole {ECO:0000250}. Note=Colocalizes with APBB1 at the nuclear
CC speckles. Colocalizes with PIN1 in the nucleus. Colocalizes with ATF4,
CC CIR1, ARHGAP33, ANKRA2, CDC42, NEK9, RAD26L, RBBP6, RPS7, TRIP4, RELB
CC and PHF1 in the centrosome. Localizes to spindle microtubules in
CC metaphase and anaphase and to the midbody during cytokinesis (By
CC similarity). {ECO:0000250}.
CC -!- TISSUE SPECIFICITY: Highly expressed in the liver.
CC {ECO:0000269|PubMed:11516946}.
CC -!- DOMAIN: Displays an autoinhibited conformation: Tyr-108 side chain
CC points into the active site, interacts with the activation loop, and
CC blocks the alphaC helix. The autoinhibitory conformation is released
CC upon binding with NEK9 (By similarity). {ECO:0000250}.
CC -!- PTM: Autophosphorylated. Phosphorylation at Ser-206 is required for its
CC activation. Phosphorylated upon IR or UV-induced DNA damage.
CC Phosphorylated by CHEK1 and CHEK2. Interaction with APBB1 down-
CC regulates phosphorylation at Thr-210 (By similarity). {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the protein kinase superfamily. NEK Ser/Thr
CC protein kinase family. NIMA subfamily. {ECO:0000305}.
