PSMA5 (Proteasome subunit alpha type-5) belongs to the peptidase T1A family. 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. Proteasomes are distributed throughout eukaryotic cells at a high concentration and cleave peptides in an ATP/ ubiquitin-dependent process in a non-lysosomal pathway. PSMA5 has been shown to interact with PLK1. This peptidase has a very broad specificity for cleavage of peptide bonds.
