Protein Structure

UniProt Annotation

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. {ECO:0000269PubMed:22341445}.

Subcellular Localization

Cytoplasm. Nucleus.

Disease Associations

Tissue Specificity

Detected in liver (at protein level). {ECO:0000269PubMed:22341445}.
