Essential component of the stress-activated protein kinase\/c-Jun N-terminal kinase (SAP\/JNK) signaling pathway. With MAP2K7\/MKK7, is the one of the only known kinase to directly activate the stress-activated protein kinase\/c-Jun N-terminal kinases MAPK8\/JNK1, MAPK9\/JNK2 and MAPK10\/JNK3. MAP2K4\/MKK4 and MAP2K7\/MKK7 both activate the JNKs by phosphorylation, but they differ in their preference for the phosphorylation site in the Thr-Pro-Tyr motif. MAP2K4 shows preference for phosphorylation of the Tyr residue and MAP2K7\/MKK7 for the Thr residue. The phosphorylation of the Thr residue by MAP2K7\/MKK7 seems to be the prerequisite for JNK activation at least in response to proinflammatory cytokines, while other stimuli activate both MAP2K4\/MKK4 and MAP2K7\/MKK7 which synergistically phosphorylate JNKs. MAP2K4 is required for maintaining peripheral lymphoid homeostasis. The MKK\/JNK signaling pathway is also involved in mitochondrial death signaling pathway, including the release cytochrome c, leading to apoptosis. Whereas MAP2K7\/MKK7 exclusively activates JNKs, MAP2K4\/MKK4 additionally activates the p38 MAPKs MAPK11, MAPK12, MAPK13 and MAPK14.\u003c\/p\u003e","brand":"BT LAB","offers":[{"title":"Default Title","offer_id":56592656695669,"sku":"BT-E5205Hu-96T","price":370.98,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0843\/2671\/1640\/files\/ELISA_Kit_main_1.jpg?v=1766393459","url":"https:\/\/www.labcart.com\/products\/human-dual-specificity-mitogen-activated-protein-kinase-4-map2k4-elisa-kit-96t","provider":"LabCart Life Science","version":"1.0","type":"link"}
