{"product_id":"rq7242","title":"PSMB4 Antibody \/ Proteasome subunit beta type 4","description":"\u003cp\u003eProteasome subunit beta type-4 also known as 20S proteasome subunit beta-7 (based on systematic nomenclature) is a protein that in humans is encoded by the PSMB4 gene. The proteasome is a multicatalytic proteinase complex with a highly ordered ring-shaped 20S core structure. The core structure is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP\/ubiquitin-dependent process in a non-lysosomal pathway. An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides. This gene encodes a member of the proteasome B-type family, also known as the T1B family, that is a 20S core beta subunit.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug \/ Rabbit","offer_id":49475436314904,"sku":"RQ7242","price":439.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_dabb6f42-8f26-4f1b-93b2-950315515600.jpg?v=1734450139","url":"https:\/\/danabiosci.com\/products\/rq7242","provider":"Dana Bioscience","version":"1.0","type":"link"}
