CC -!- FUNCTION: Component of the 20S core proteasome complex involved in CC the proteolytic degradation of most intracellular proteins. This CC complex plays numerous essential roles within the cell by CC associating with different regulatory particles. Associated with CC two 19S regulatory particles, forms the 26S proteasome and thus CC participates in the ATP-dependent degradation of ubiquitinated CC proteins. The 26S proteasome plays a key role in the maintenance CC of protein homeostasis by removing misfolded or damaged proteins CC that could impair cellular functions, and by removing proteins CC whose functions are no longer required. Associated with the PA200 CC or PA28, the 20S proteasome mediates ubiquitin-independent protein CC degradation. This type of proteolysis is required in several CC pathways including spermatogenesis (20S-PA200 complex) or CC generation of a subset of MHC class I-presented antigenic peptides CC (20S-PA28 complex). {ECO:0000269|PubMed:16581775, CC ECO:0000269|PubMed:22341445}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Cleavage of peptide bonds with very broad specificity.; CC EC=3.4.25.1; Evidence={ECO:0000255|PROSITE-ProRule:PRU00808}; CC -!- SUBUNIT: The 26S proteasome consists of a 20S proteasome core and CC two 19S regulatory subunits. The 20S proteasome core is a barrel- CC shaped complex made of 28 subunits that are arranged in four CC stacked rings. The two outer rings are each formed by seven alpha CC subunits, and the two inner rings are formed by seven beta CC subunits. The proteolytic activity is exerted by three beta- CC subunits PSMB5, PSMB6 and PSMB7 (PubMed:16857966, CC PubMed:22341445). {ECO:0000269|PubMed:16857966, CC ECO:0000269|PubMed:22341445}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:22078707}. CC Nucleus {ECO:0000269|PubMed:22078707}. Note=Colocalizes with TRIM5 CC in the cytoplasmic bodies. {ECO:0000269|PubMed:22078707}. CC -!- TISSUE SPECIFICITY: Detected in liver (at protein level). CC {ECO:0000269|PubMed:22341445}. CC -!- SIMILARITY: Belongs to the peptidase T1A family. CC {ECO:0000255|PROSITE-ProRule:PRU00808}.
