CC -!- FUNCTION: Non-catalytic component of the 20S core proteasome complex
CC involved in the proteolytic degradation of most intracellular proteins.
CC This complex plays numerous essential roles within the cell by
CC associating with different regulatory particles. Associated with two
CC 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 of
CC protein homeostasis by removing misfolded or damaged proteins that
CC could impair cellular functions, and by removing proteins whose
CC functions are no longer required. Associated with the PA200 or PA28,
CC the 20S proteasome mediates ubiquitin-independent protein degradation.
CC This type of proteolysis is required in several pathways including
CC spermatogenesis (20S-PA200 complex) or generation of a subset of MHC
CC class I-presented antigenic peptides (20S-PA28 complex).
CC {ECO:0000250|UniProtKB:P49720}.
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:P49720}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P49720}. Nucleus
CC {ECO:0000250|UniProtKB:P49720}. 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:P49720}.
CC -!- SIMILARITY: Belongs to the peptidase T1B family. {ECO:0000255|PROSITE-
CC ProRule:PRU00809}.
