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}.
