特徴

• The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator.
• The 20S core 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.
• The 19S regulator is composed of a base, which contains 6 ATPase subunits and 2 non-ATPase subunits, and a lid, which contains up to 10 non-ATPase 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.
• The immunoproteasome contains an alternate regulator, referred to as the 11S regulator or PA28, that replaces the 19S regulator.
• Three subunits (alpha, beta and gamma) of the 11S regulator have been identified.
• This gene encodes the alpha subunit of the 11S regulator, one of the two 11S subunits that is induced by gamma-interferon.
• Three alpha and three beta subunits combine to form a heterohexameric ring.
• Two transcripts encoding different isoforms have been identified.The 26S proteasome is a multicatalytic proteinase complex with a highly ordered structure composed of 2 complexes, a 20S core and a 19S regulator.
