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: The 26S proteasome consists of a 20S proteasome core and two
CC 19S regulatory subunits. The 20S proteasome core is composed of 28
CC subunits that are arranged in four stacked rings, resulting in a
CC barrel-shaped structure. The two end rings are each formed by seven
CC alpha subunits, and the two central rings are each formed by seven beta
CC subunits. The catalytic chamber with the active sites is on the inside
CC of the barrel (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}. Nucleus {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the peptidase T1A family. {ECO:0000255|PROSITE-
CC ProRule:PRU00808}.
