  • FunctionPleiotropic regulator of mitotic progression, participating in the control of spindle dynamics and chromosome separation. Phosphorylates different histones, myelin basic protein, beta-casein, and BICD2. Phosphorylates histone H3 on serine and threonine residues and beta-casein on serine residues. Important for G1/S transition and S phase progression.
  • Tissue specificityMost abundant in heart, liver, kidney and testis. Also expressed in smooth muscle cells and fibroblasts.
  • Sequence similaritiesBelongs to the protein kinase superfamily. NEK Ser/Thr protein kinase family. NIMA subfamily.
    Contains 1 protein kinase domain.
    Contains 6 RCC1 repeats.
  • Developmental stageExpression varied mildly across the cell cycle, with highest expression observed in G1 and stationary-phase cells.
  • DomainDimerizes through its coiled-coil domain.
  • Post-translational
    Autophosphorylated on serine and threonine residues. When complexed with FACT, exhibits markedly elevated phosphorylation on Thr-210. During mitosis, not phosphorylated on Thr-210. Phosphorylated by CDK1 in vitro.
  • Cellular localizationCytoplasm. Nucleus.
