  • FunctionInvolved in both the initiation and regulation of meiosis, mitosis, and postmitotic functions in differentiated cells by phosphorylating a number of transcription factors such as ELK-1. Phosphorylates EIF4EBP1; required for initiation of translation. Phosphorylates microtubule-associated protein 2 (MAP2). Phosphorylates SPZ1 (By similarity). Phosphorylates heat shock factor protein 4 (HSF4).
  • Sequence similaritiesBelongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
    Contains 1 protein kinase domain.
  • DomainThe TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
  • Post-translational
    Dually phosphorylated on Thr-202 and Tyr-204, which activates the enzyme. Dephosphorylated by PTPRJ at Tyr-204.
