Summary: Enables MAP kinase activity. Involved in several processes, including defense response to other organism; determination of adult lifespan; and regulation of signal transduction. Predicted to be active in cytoplasm and nucleus. Is expressed in several structures, including embryonic/larval midgut primordium; gastric caecum; gut section; larval muscle cell; and somatic precursor cell. Human ortholog(s) of this gene implicated in colon cancer; colorectal carcinoma; nasopharynx carcinoma; and rectum cancer. Orthologous to human MAPK14 (mitogen-activated protein kinase 14).
