  • Function
    Phosphorylates MAP kinase p38. Seems to be active only in mitosis. May also play a role in the activation of lymphoid cells. When phosphorylated, forms a complex with TP53, leading to TP53 destabilization and attenuation of G2/M checkpoint during doxorubicin-induced DNA damage.
  • Tissue specificity
    Expressed in the testis and placenta. In the testis, restrictedly expressed in outer cell layer of seminiferous tubules.
  • Sequence similarities
    Belongs to the protein kinase superfamily. Ser/Thr protein kinase family. MAP kinase kinase subfamily.
    Contains 1 protein kinase domain.
  • Post-translational
    Phosphorylated; in a cell-cycle dependent manner at mitosis.
