  • Application notes
    Is unsuitable for Flow Cyt or ICC/IF.
  • Target

    • Function

      Phosphorylates microtubule-associated protein 2 (MAP2). May promote entry in the cell cycle.
    • Tissue specificity

      Highest expression in the skeletal muscle, followed by the brain. Also found in heart, placenta, lung, liver, pancreas, kidney and skin fibroblasts.
    • Sequence similarities

      Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
      Contains 1 protein kinase domain.
    • Domain

      The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
    • Post-translational

      Dually phosphorylated on Thr-626 and Tyr-628, which activates the enzyme.
