Responds to activation by environmental stress and pro-inflammatory cytokines by phosphorylating a number of transcription factors, and thus regulating transcriptional activity (By similarity). Regulates morphogenic cell movements, controlling convergent extension during gastrulation. May play a role in the regulation of the circadian clock (By similarity). ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-[protein] ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-threonyl-[protein] Activated by threonine and tyrosine phosphorylation, potentially by the dual-specificity kinase, MKK7. Indirectly activated by Wnt5a. Strongly expressed in presumptive ectoderm and mesoderm regions and weakly expressed in endoderm regions during early stages of embryo development. Expressed in the head and dorsal regions during neurula and tailbud stages. The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases. Dually phosphorylated on Thr-183 and Tyr-185, which activates the enzyme. Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
