Enzyme Function 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. This subunit is involved in antigen processing to generate class I binding peptides.

Interact With
Induction INDUCTION: Up-regulated by interferon gamma (at protein level). Up-regulated by theophylline (THP), a reprotoxic agent thought to induce infertility. {ECO:0000269|PubMed:16988215}.
Subcellular Location SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|PROSITE-ProRule:PRU00809}. Nucleus {ECO:0000250}.
Modified Residue MOD_RES 53; /note=N6-acetyllysine; /evidence=ECO:0000250|UniProtKB:P28065; MOD_RES 109; /note=N6-acetyllysine; /evidence=ECO:0000250|UniProtKB:P28065
Post Translational Modification PTM: Autocleaved. The resulting N-terminal Thr residue of the mature subunit is responsible for the nucleophile proteolytic activity. {ECO:0000250|UniProtKB:O35955}.
