CC -!- FUNCTION: Non-catalytic component of the proteasome, a multicatalytic
CC proteinase complex which is characterized by its ability to cleave
CC peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group
CC at neutral or slightly basic pH. The proteasome has an ATP-dependent
CC proteolytic activity (By similarity). {ECO:0000250}.
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:0000255|PROSITE-ProRule:PRU00809}.
CC Nucleus {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the peptidase T1B family. {ECO:0000255|PROSITE-
CC ProRule:PRU00809}.
CC -!- CAUTION: The gene for this protein is duplicated in strains AX3 and
CC AX4. These strains contain a duplication of a segment of 750 kb of
CC chromosome 2 compared to the corresponding sequence in strain AX2.
CC {ECO:0000305}.
