  • Application notes
    Is unsuitable for IP.
  • Target

    • Function
      Pleiotropic 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 specificity
      Most abundant in heart, liver, kidney and testis. Also expressed in smooth muscle cells and fibroblasts.
    • Sequence similarities
      Belongs to the protein kinase superfamily. NEK Ser/Thr protein kinase family. NIMA subfamily.
      Contains 1 protein kinase domain.
      Contains 6 RCC1 repeats.
    • Developmental stage
      Expression varied mildly across the cell cycle, with highest expression observed in G1 and stationary-phase cells.
    • Domain
      Dimerizes 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 localization
      Cytoplasm. Nucleus.
