What are Proteasome Inhibitors?

All eukaryotic cells contain protein complexes called proteasomes. Proteasomes maintain the concentration of proteins in cells as well as disposing of unneeded or damage proteins. The process of degrading unwanted proteins is called proteolysis and the enzymes that carry out this process are called proteases. The degradation process produces short chains of amino acids called peptides that can be recycled […]
