CC -!- FUNCTION: Component of the 20S core proteasome complex involved in the CC proteolytic degradation of most intracellular proteins. This complex CC plays numerous essential roles within the cell by associating with CC different regulatory particles. Associated with two 19S regulatory CC particles, forms the 26S proteasome and thus participates in the ATP- CC dependent degradation of ubiquitinated proteins. The 26S proteasome CC plays a key role in the maintenance of protein homeostasis by removing CC misfolded or damaged proteins that could impair cellular functions, and CC by removing proteins whose functions are no longer required. Associated CC with the PA200 or PA28, the 20S proteasome mediates ubiquitin- CC independent protein degradation. This type of proteolysis is required CC in several 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 two CC 19S regulatory subunits. The 20S proteasome core is a barrel-shaped CC complex made of 28 subunits that are arranged in four stacked rings. CC The two outer rings are each formed by seven alpha subunits, and the CC two inner rings are formed by seven beta subunits. The proteolytic CC activity is exerted by three beta-subunits PSMB5, PSMB6 and PSMB7 CC (PubMed:16857966, PubMed:22341445). {ECO:0000269|PubMed:16857966, CC ECO:0000269|PubMed:22341445}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:22078707}. Nucleus CC {ECO:0000269|PubMed:22078707}. Note=Colocalizes with TRIM5 in the CC 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. {ECO:0000255|PROSITE- CC ProRule:PRU00808}.
