Catalysis of the phosphorylation and activation of members of the JUN family, a gene family that encodes nuclear transcription factors. Catalysis of the phosphorylation of proteins. A family of protein kinases that perform a crucial step in relaying signals from the plasma membrane to the nucleus. Strongly activated by stress signals such as heat or osmotic shock, DNA-damaging agents, inhibitors of protein synthesis and pro-inflammatory cytokines. Catalysis of the phosphorylation of proteins. Mitogen-activated protein kinase; a family of protein kinases that perform a crucial step in relaying signals from the plasma membrane to the nucleus. They are activated by a wide range of proliferation- or differentiation-inducing signals; activation is strong with agonists such as polypeptide growth factors and tumor-promoting phorbol esters, but weak (in most cell backgrounds) by stress stimuli.
