CC -!- FUNCTION: The proteasome is a multicatalytic proteinase complex which
CC is characterized by its ability to cleave peptides with Arg, Phe, Tyr,
CC Leu, and Glu adjacent to the leaving group at neutral or slightly basic
CC pH. The proteasome has an ATP-dependent proteolytic activity.
CC -!- SUBUNIT: Component of the 20S core complex of the 26S proteasome. The
CC 26S proteasome is composed of a core protease (CP), known as the 20S
CC proteasome, capped at one or both ends by the 19S regulatory particle
CC (RP/PA700). The 20S proteasome core is composed of 28 subunits that are
CC arranged in four stacked rings, resulting in a barrel-shaped structure.
CC The two end rings are each formed by seven alpha subunits, and the two
CC central rings are each formed by seven beta subunits. The catalytic
CC chamber with the active sites is on the inside of the barrel.

CC ECO:0000269|PubMed:20516081}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the peptidase T1A family. {ECO:0000255|PROSITE-
CC ProRule:PRU00808}.
