{"product_id":"new-product-282815","title":"ERK1 polyclonal antibody","description":"\u003cp\u003eMitogen-activated protein kinase (MAPK) signaling pathways involve two closely related MAP kinases, known as extracellular-signal-related kinase 1 (ERK 1, p44) and 2 (ERK 2, p42). Growth factors, steroid hormones, G protein-coupled receptor ligands and neurotransmitters can initiate MAPK signaling pathways. Activation of ERK 1 and ERK 2 requires phosphorylation by upstream kinases such as MAP kinasekinase (MEK), MEK kinase and Raf-1. ERK 1 and ERK 2 phosphorylation can occur at specific tyrosine and threonine sites mapping within consensus motifs that include the threonine-glutamate-tyrosine motif. ERK activation leads to dimerization with other ERKs and subsequent localization to the nucleus. Active ERK dimers phosphorylate serine and threonine residues on nuclear proteins and influence a host of responses that include proliferation, differentiation, transcription regulation and development. The human ERK 1 gene maps to chromosome 16p12-p11.2 and encodes a 379 amino acid protein that shares 83% sequence identity to ERK 2.\u003c\/p\u003e","brand":"ABCbiolab","offers":[{"title":"100ul \/ Rabbit \/ Human, Mouse","offer_id":45809295982872,"sku":"ABCBW10905","price":448.0,"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_d10083d4-ba2f-41fc-9633-ff1793adbfb4.png?v=1689757680","url":"https:\/\/danabiosci.com\/products\/new-product-282815","provider":"Dana Bioscience","version":"1.0","type":"link"}
