Protein 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. / ATP + a protein = ADP + a phosphoprotein. / Activated by phosphorylation.

Protein tissue specificity

Expressed in the testis and placenta. In the testis, restrictedly expressed in outer cell layer of seminiferous tubules.

Protein sequence and domain

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

Protein post-translational modifications

Phosphorylated; in a cell-cycle dependent manner at mitosis.
