Protein Structure
UniProt Annotation
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. {ECO:0000269PubMed:10781613, ECO:0000269PubMed:17482142}.
Subcellular Localization
Disease Associations
Tissue Specificity Expressed in the testis and placenta. In the testis, restrictedly expressed in outer cell layer of seminiferous tubules. {ECO:0000269PubMed:10781613, ECO:0000269PubMed:11378444}.
