The proteasome is a multicatalytic proteinase complex with a highly ordered ring-shaped 20S core structure.
The core structure is composed of 4 rings of 28 non-identical subunits; 2 rings are composed of 7 alpha subunits and 2 rings are composed of 7 beta subunits.
Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ubiquitin-dependent process in a non-lysosomal pathway.
An essential function of a modified proteasome, the immunoproteasome, is the processing of class I MHC peptides.
PSMA3 (proteasome subunit alpha 3) encodes a member of the peptidase T1A family, that is a 20S core alpha subunit.
Two alternative transcripts encoding different isoforms have been identified.
