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:0000250|UniProtKB:P60900}.
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 Interacts with ALKBH4. {ECO:0000250|UniProtKB:P60900}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P60900,
CC ECO:0000250|UniProtKB:Q9QUM9}. Nucleus {ECO:0000250|UniProtKB:P60900}.
CC Note=Translocated from the cytoplasm into the nucleus following
CC interaction with AKIRIN2, which bridges the proteasome with the nuclear
CC import receptor IPO9 (By similarity). Colocalizes with TRIM5 in
CC cytoplasmic bodies (By similarity). {ECO:0000250|UniProtKB:P60900,
CC ECO:0000250|UniProtKB:Q9QUM9}.
CC -!- SIMILARITY: Belongs to the peptidase T1A family. {ECO:0000255|PROSITE-
CC ProRule:PRU00808}.
