{"product_id":"abm206780","title":"Phospho-20S Proteasome  Alpha3 (S250) Polyclonal Antibody","description":"\u003ch3\u003eBackground\u003c\/h3\u003e\u003cp\u003eThe 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. PSMA3 (proteasome subunit alpha 3) encodes a member of the peptidase T1A family, that is a 20S core alpha subunit. Two alternative transcripts encoding different isoforms have been identified.\u003c\/p\u003e\u003cp\u003e\u003cem\u003ePackaging image shown for reference.
