{"product_id":"new-product-230071","title":"MEK-3 (phospho-S189) polyclonal antibody","description":"\u003cp\u003eThe prototype member of this family, designated MAP kinase kinase, or MEK-1, specifically phosphorylates the MAP kinaseegulatory threonine and tyrosine residues present in thehr-Glu-Tyr motif of ERK. A second MEK family member, MEK-2, resembles MEK-1 in its substrate specificity. MEK-3 (or MKK-3) functions to activate p38 MAP kinase, and MEK-4 (also called SEK1 or MKK-4) activates both p38 and JNK MAP kinases. MEK-5 appears to specifically phosphorylate ERK5, whereas MEK-6hosphorylates p38 and p38b. MEK-7 (or MKK-7) phosphorylates and activates the JNK signal transduction pathway.\u003c\/p\u003e","brand":"Bioworld","offers":[{"title":"100ul \/ Rabbit \/ Human,Mouse,Rat","offer_id":47662720581912,"sku":"BS4123","price":348.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/products\/BIOWORLD_d411ffbf-7075-477a-bc6d-bddec625542c.jpg?v=1707493018","url":"https:\/\/danabiosci.com\/products\/new-product-230071","provider":"Dana Bioscience","version":"1.0","type":"link"}
