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.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eActivity assay development for kinetics, substrate scope, and inhibitor\/activator profiling.\u003c\/li\u003e\n\u003cli\u003eUse of recombinant standards to improve assay calibration and cross-study comparability.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003ePhosphorylates MAP kinase p38.
