thumb|Diagram of an ectodomain shedding ADAM metalloprotease. Sheddases are membrane-bound enzymes that cleave extracellular portions of transmembrane proteins, releasing the soluble ectodomains from the cell surface. Many sheddases are members of the ADAM or aspartic protease (BACE) protein families.

These enzymes can activate a transmembrane protein if it is a receptor (e.g., HER2), or cut off the part of the transmembrane protein which has already bound an agonist (e.g., in the case of EGFR), allowing this agonist to go and stimulate a receptor on another cell. Hence, sheddases demultiply the yield of agonists. Sheddase inhibitors active on ADAM10 and ADAM17 can potentiate anti-cancer therapy.
