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). Within the 20S core complex, PSMB6 displays a CC peptidylglutamyl-hydrolyzing activity also termed postacidic or CC caspase-like activity, meaning that the peptides bond hydrolysis occurs CC directly after acidic residues. {ECO:0000250|UniProtKB:P28072}. CC -!- CATALYTIC ACTIVITY: CC Reaction=Cleavage of peptide bonds with very broad specificity.; CC EC=3.4.25.1; Evidence={ECO:0000250|UniProtKB:P28072}; 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 {ECO:0000250|UniProtKB:P28072}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P28072}. Nucleus CC {ECO:0000250|UniProtKB:P28072}. Note=Translocated from the cytoplasm CC into the nucleus following interaction with AKIRIN2, which bridges the CC proteasome with the nuclear import receptor IPO9. CC {ECO:0000250|UniProtKB:P28072}. CC -!- SIMILARITY: Belongs to the peptidase T1B family. {ECO:0000255|PROSITE- CC ProRule:PRU00809}.
