Clin. Invest. 125:4196-4211(2015). CC -!- FUNCTION: The proteasome is a multicatalytic proteinase complex which CC is characterized by its ability to cleave peptides with Arg, Phe, Tyr, CC Leu, and Glu adjacent to the leaving group at neutral or slightly basic CC pH. The proteasome has an ATP-dependent proteolytic activity. This CC subunit is involved in antigen processing to generate class I binding CC peptides. Replacement of PSMB6 by PSMB9 increases the capacity of the CC immunoproteasome to cleave model peptides after hydrophobic and basic CC residues. {ECO:0000269|PubMed:8163024}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Cleavage of peptide bonds with very broad specificity.; CC EC=3.4.25.1; CC -!- SUBUNIT: The 26S proteasome consists of a 20S proteasome core and two CC 19S regulatory subunits. The 20S proteasome core is composed of 28 CC subunits that are arranged in four stacked rings, resulting in a CC barrel-shaped structure. The two end rings are each formed by seven CC alpha subunits, and the two central rings are each formed by seven beta CC subunits. The catalytic chamber with the active sites is on the inside CC of the barrel. Component of the immunoproteasome, where it displaces CC the equivalent housekeeping subunit PSMB6. Component of the CC spermatoproteasome, a form of the proteasome specifically found in CC testis. {ECO:0000269|PubMed:16957778}.

CC -!- DISEASE: Proteasome-associated autoinflammatory syndrome 3 (PRAAS3) CC [MIM:617591]: An autoinflammatory disorder characterized by onset in CC early infancy and recurrent fever, nodular dermatitis, myositis, CC panniculitis-induced lipodystrophy, lymphadenopathy, and immune CC dysregulation. Variable accompanying features may include joint CC contractures, hepatosplenomegaly, anemia, thrombocytopenia, recurrent CC infections, autoantibodies, and hypergammaglobulinemia. Some patients CC may have intracranial calcifications. PRAAS3 inheritance is autosomal CC recessive or digenic. {ECO:0000269|PubMed:26524591}. Note=The disease CC may be caused by variants affecting distinct genetic loci, including CC the gene represented in this entry. CC -!- MISCELLANEOUS: Encoded in the MHC class II region. CC -!- MISCELLANEOUS: A model for self-activation in which residue Thr-21 CC serves as nucleophile and Lys-53 as proton donor/acceptor has been CC proposed. Subunit processing of mammalian beta-subunits proceeds via a CC novel ordered two-step mechanism involving autocatalysis.
