{"product_id":"new-product-394611","title":"ZAP70 (T286) polyclonal antibody","description":"\u003cp\u003eThe activation of T lymphocytes by antigens is mediated by the T cell receptor (TCR), which is a multisubunit complex assembled from at least six different genes . The TCR subunits include the Ti a and b chains, the CD3 g , d and e chains and a z -containing homodimer or heterodimer . The protein tyrosine kinase ZAP-70 binds to the phosphorylated immunoreceptor tyrosine-base activation motifs (ITAMs) of the TCR z chain through two src-homology (SH2) domains . This binding results in the phosphorylation of ZAP-70 on multiple tyrosine residues, including Tyr292 and Tyr319 . ZAP-70 is autophosphorylated on Tyr292, which is thought to negatively regulate ZAP-70 function in lymphocytes . Alternatively, ZAP-70 is positively regulated by phosphorylation on Tyr319, which mediates the SH2-dependent interaction between Lck and ZAP-70 .\u003c\/p\u003e","brand":"Bioworld","offers":[{"title":"100ul \/ Rabbit \/ Human,Rat","offer_id":44092017180896,"sku":"BS1610","price":325.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/9330\/8896\/products\/bioWORLD-Logo-New_1617713956_b662aeff-1da5-4c94-8fe1-954de8083b6c.png?v=1689711014","url":"https:\/\/rndmate.com\/products\/new-product-394611","provider":"알앤디메이트","version":"1.0","type":"link"}
