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. {ECO:0000250|UniProtKB:Q60177}.
CC   -!- SUBUNIT: Composed of two subunits, alpha and beta. The complex is
CC       formed of four rings. The two outer rings are each composed of seven
CC       alpha subunits. The two inner rings are each composed of seven beta
CC       subunits (By similarity). {ECO:0000250|UniProtKB:Q9V2V5}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the peptidase T1A family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00808}.
