{"product_id":"new-product-275153","title":"CD3G polyclonal antibody","description":"\u003cp\u003eThe T cell antigen receptor (TCR) recognizesforeign antigens and translates such recognition eventsinto intracellularsignalsthat elicit a change in the cell froma dormant to an activated state.Much of this signaling processcan be attributed to a multisubunitcomplex of proteins that associates directly with the TCR. Thiscomplex has been designated CD3 (cluster of differentiation 3). It iscomposed of five invariant polypeptide chainsthat associate to form three dimers: a heterodimer of γ and ε chains(γε), a heterodimer of δ and ε chains(δε) and a homodimer of two ζ chains(ζζ) or a heterodimer of ζ and η chains(ζη). The ζ and η chains are encoded bythe same gene but differ in theircarboxyl-terminal ends due to an alternative splicing event. The γ, ε and δ chains each contain a single copy of a conserved immunoreceptor tyrosine-based activationmotif (ITAM). In contrast, the ζ chain containsthree consecutive copies of the same motif. Phosphorylated ITAMs act as docking sitesfor protein kinases such as ZAP-70 and Syk and are also capable of regulating theirkinase activity. The crystalstructure of ZAP-70’s SH2 domains bound to the ζ chain ITAMs has been solved.\u003c\/p\u003e","brand":"ABCbiolab","offers":[{"title":"100ul \/ Rabbit \/ Human,Mouse,Rat","offer_id":45804926632216,"sku":"ABCBW03243","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_64daea5e-6cba-41b5-8652-d5f773f9aeb8.png?v=1689739323","url":"https:\/\/danabiosci.com\/products\/new-product-275153","provider":"Dana Bioscience","version":"1.0","type":"link"}
