Natl. Acad. Sci. U.S.A. 118:0-0(2021). 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 -!- 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}.
