CC -!- FUNCTION: The proteasome degrades poly-ubiquitinated proteins in the
CC cytoplasm and in the nucleus. It is essential for the regulated
CC turnover of proteins and for the removal of misfolded proteins. The
CC proteasome is a multicatalytic proteinase complex that is characterized
CC by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu
CC adjacent to the leaving group at neutral or slightly basic pH. It has
CC an ATP-dependent 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:0000250}. Nucleus {ECO:0000250}.
CC -!- DEVELOPMENTAL STAGE: Expressed in late sporogonial stages.
CC {ECO:0000269|PubMed:16691553}.
CC -!- SIMILARITY: Belongs to the peptidase T1A family. {ECO:0000255|PROSITE-
CC ProRule:PRU00808}.
