CC -!- FUNCTION: The proteasome is a multicatalytic proteinase complex CC which is characterized by its ability to cleave peptides with Arg, CC 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:0000269|PubMed:22341445}. CC -!- CATALYTIC ACTIVITY: Cleavage of peptide bonds with very broad CC specificity. {ECO:0000255|PROSITE-ProRule:PRU00808}. CC -!- SUBUNIT: The 26S proteasome consists of a 20S proteasome core and CC two 19S regulatory subunits. The 20S proteasome core is composed CC of 28 subunits that are arranged in four stacked rings, resulting CC in a barrel-shaped structure. The two end rings are each formed by CC seven alpha subunits, and the two central rings are each formed by CC seven beta subunits. The catalytic chamber with the active sites CC is on the inside of the barrel. {ECO:0000269|PubMed:16857966, CC ECO:0000269|PubMed:22341445}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:22078707}. CC Nucleus {ECO:0000269|PubMed:22078707}. Cytoplasm, P-body CC {ECO:0000269|PubMed:22078707}. Note=Colocalizes with TRIM5 in the CC cytoplasmic bodies. CC -!- TISSUE SPECIFICITY: Detected in liver (at protein level). CC {ECO:0000269|PubMed:22341445}. CC -!- SIMILARITY: Belongs to the peptidase T1A family. CC {ECO:0000255|PROSITE-ProRule:PRU00808}.
