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 -!- 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. This
CC subunit is involved in antigen processing to generate class I binding
CC peptides. {ECO:0000256|ARBA:ARBA00025456}.
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 -!- 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}.
