General annotation (Comments)

Function	The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity By similarity.
Catalytic activity	Cleavage of peptide bonds with very broad specificity.
Subunit structure	The 26S proteasome consists of a 20S proteasome core and two 19S regulatory subunits. The 20S proteasome core is composed of 28 subunits that are arranged in four stacked rings, resulting in a barrel-shaped structure. The two end rings are each formed by seven alpha subunits, and the two central rings are each formed by seven beta subunits. The catalytic chamber with the active sites is on the inside of the barrel By similarity.
Subcellular location	Cytoplasm By similarity. Nucleus By similarity.
Sequence similarities	Belongs to the peptidase T1A family.
