{"product_id":"ube3b-polyclonal-antibody-100ul","title":"UBE3B Polyclonal Antibody, 100ul","description":"\u003cp\u003eThe modification of proteins with ubiquitin is an important cellular mechanism for targeting abnormal or short-lived proteins for degradation. Ubiquitination involves at least three classes of enzymes: e1 ubiquitin-activating enzymes, E2 ubiquitin-conjugating enzymes, and E3 ubiquitin-protein ligases. UBE3B (ubiquitin protein ligase E3B) encodes a member of the E3 ubiquitin-conjugating enzyme family which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme and transfers the ubiquitin to the targeted substrates. A HECT (homology to E6-AP C-terminus) domain in the C-terminus of the longer isoform of this protein is the catalytic site of ubiquitin transfer and forms a complex with E2 conjugases. Shorter isoforms of this protein which lack the C-terminal HECT domain are therefore unlikely to bind E2 enzymes. Alternatively spliced transcript variants encoding distinct isoforms have been identified for UBE3B.\u003c\/p\u003e","brand":"BT LAB","offers":[{"title":"Default Title","offer_id":56516839375221,"sku":"BT-AP09365-100ul","price":247.5,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0843\/2671\/1640\/files\/Antibody_main_Dungeon4_b9646263-7fda-4fd2-82e8-9047834a0edb.jpg?v=1767148117","url":"https:\/\/www.labcart.com\/products\/ube3b-polyclonal-antibody-100ul","provider":"LabCart Life Science","version":"1.0","type":"link"}
