The p44\/42 MAPK (Erk1\/2) signaling pathway can be activated in response to a diverse range of extracellular stimuli including mitogens, growth factors, and cytokines, and research investigators consider it an important target in the diagnosis and treatment of cancer. Upon stimulation, a sequential three-part protein kinase cascade is initiated, consisting of a MAP kinase kinase kinase (MAPKKK or MAP3K), a MAP kinase kinase (MAPKK or MAP2K), and a MAP kinase (MAPK). Multiple p44\/42 MAP3Ks have been identified, including members of the Raf family, as well as Mos and Tpl2\/COT. MEK1 and MEK2 are the primary MAPKKs in this pathway. MEK1 and MEK2 activate p44 and p42 through phosphorylation of activation loop residues Thr202\/Tyr204 and Thr185\/Tyr187, respectively. Several downstream targets of p44\/42 have been identified, including p90RSK and the transcription factor Elk-1. p44\/42 are negatively regulated by a family of dual-specificity (Thr\/Tyr) MAPK phosphatases, known as DUSPs or MKPs, along with MEK inhibitors, such as U0126 and PD98059.\u003c\/p\u003e","brand":"ABCbiolab","offers":[{"title":"100ul \/ Rabbit \/ Human,Mouse,Rat","offer_id":45803087626520,"sku":"ABCBW00021","price":325.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/758-7580448_monoclonal-antibody-png-transparent-png_bade2d4f-b03a-471a-8957-25ba067ce54c.png?v=1689731407","url":"https:\/\/danabiosci.com\/products\/new-product-271931","provider":"Dana Bioscience","version":"1.0","type":"link"}
