ADAM17_MPD is the membrane-proximal domain of a family of disintegrin and metalloproteinase domain-containing protein 17 found in metazoan species. ADAM17 is a major sheddase that is responsible for the regulation of a wide range of biological processes, such as cellular differentiation, regeneration, and cancer progression. This MPD region acts as the sheddase switch. PDI or protein-disulfide isomerase interacts with ADAM17 and to down-regulate its enzymatic activity. The interaction is directly with the MPD, the region of dimerisation and substrate recognition, where it catalyses an isomerisation of disulfide bridges within the thioredoxin motif CXXC. this isomerisation results in a major structural change between an active, open state and an inactive, closed state of the MPD. This change is thought to act as a molecular switch, allowing a global reorientation of the extracellular domains in ADAM17 and regulating its shedding activity [1].

This domain is found in a family of integral membrane proteins that are related to Drosophila rhomboid protein Swiss:P20350. Members of this family are mainly found in bacteria and eukaryotes. Rhomboid promotes the cleavage of the membrane-anchored TGF-alpha-like growth factor Spitz, allowing it to activate the Drosophila EGF receptor. Analysis has shown that Rhomboid-1 is an intramembrane serine protease [2,3,4] (EC:3.4.21.105). Parasite-encoded rhomboid enzymes are also important for invasion of host cells by Toxoplasma and the malaria parasite [5]. This domain shows six transmembrane helices.
