{"product_id":"new-product-274420","title":"Cortactin (phospho-Y421) polyclonal antibody","description":"\u003cp\u003eCortactin is an 80\/85 kDa cytoskeleton protein that facilitates assembly of cortical actin. Cortactin is widely expressed in most adherent cells and is a prominent substrate of protein tyrosine kinase Src in vivo and in vitro. The protein sequence of cortactin contains multiple amino terminal tandem repeats of a unique 37 amino acid sequence, which associates with actin, and a Src homology 3 (SH3) domain at the carboxyl terminus. Between the repeat and the SH3 domain, there is an alpha helical structure followed by a proline rich region. Between the proline rich region and the SH3 domain, there are a series of Src phosphorylation sites (Tyr421, Tyr470, and Tyr486). In vitro, cortactin binds to and cross links F actin into meshworks.\u003c\/p\u003e","brand":"ABCbiolab","offers":[{"title":"100ul \/ Rabbit \/ Human,Mouse,Rat","offer_id":45804131418392,"sku":"ABCBW02510","price":348.0,"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_12ce17a6-c435-4c9d-9917-1f3a6866bf3d.png?v=1689737645","url":"https:\/\/danabiosci.com\/products\/new-product-274420","provider":"Dana Bioscience","version":"1.0","type":"link"}
