Predicted to enable ATP binding activity; MAP kinase activity; and magnesium ion binding activity. Predicted to be involved in several processes, including intracellular signal transduction; myoblast differentiation; and peptidyl-serine phosphorylation. Predicted to act upstream of or within phosphorylation. Predicted to be located in nucleoplasm. Predicted to be active in cytoplasm and nucleus. Is expressed in cap mesenchyme; lung mesenchyme; metanephros; and olfactory epithelium. Orthologous to human MAPK12 (mitogen-activated protein kinase 12).
