CC -!- FUNCTION: Component of the proteasome, a multicatalytic proteinase
CC complex which is characterized by its ability to cleave peptides with
CC Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or
CC slightly basic pH. The proteasome has an ATP-dependent proteolytic
CC activity. {ECO:0000256|RuleBase:RU004203}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Cleavage of peptide bonds with very broad specificity.;
CC EC=3.4.25.1; Evidence={ECO:0000256|ARBA:ARBA00001198};
CC -!- SUBUNIT: Component of the proteasome complex.
CC {ECO:0000256|RuleBase:RU004203}.
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. {ECO:0000256|ARBA:ARBA00026071}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|RuleBase:RU004203}.
CC Nucleus {ECO:0000256|RuleBase:RU004203}.
CC -!- SIMILARITY: Belongs to the peptidase T1B family.
CC {ECO:0000256|RuleBase:RU004203}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:PHH51147.1}.
