Disease

[ADA17_HUMAN] Defects in ADAM17 are a cause of neonatal inflammatory skin and bowel disease (NISBD) [MIM:614328]. NISBD is a disorder characterized by inflammatory features with neonatal onset, involving the skin, hair, and gut. The skin lesions involve perioral and perianal erythema, psoriasiform erythroderma, with flares of erythema, scaling, and widespread pustules. Gastrointestinal symptoms include malabsorptive diarrhea that is exacerbated by intercurrent gastrointestinal infections. The hair is short or broken, and the eyelashes and eyebrows are wiry and disorganized.^[1]

Function

[ADA17_HUMAN] Cleaves the membrane-bound precursor of TNF-alpha to its mature soluble form. Responsible for the proteolytical release of soluble JAM3 from endothelial cells surface. Responsible for the proteolytic release of several other cell-surface proteins, including p75 TNF-receptor, interleukin 1 receptor type II, p55 TNF-receptor, transforming growth factor-alpha, L-selectin, growth hormone receptor, MUC1 and the amyloid precursor protein. Also involved in the activation of Notch pathway (By similarity).^[2] ^[3]

Publication Abstract from PubMed

A disintegrin and metalloprotease-17 (ADAM17) is a major sheddase responsible for the regulation of a wide range of biological processes, like cellular differentiation, regeneration, or cancer progression. Hitherto, the mechanism regulating the enzymatic activity of ADAM17 is poorly understood. Recently, protein-disulfide isomerase (PDI) was shown to interact with ADAM17 and to down-regulate its enzymatic activity. Here we demonstrate by NMR spectroscopy and tandem-mass spectrometry that PDI directly interacts with the membrane-proximal domain (MPD), a domain of ADAM17 involved in its dimerization and substrate recognition. PDI catalyzes an isomerization of disulfide bridges within the thioredoxin motif C600XXC603 of the MPD and results in a drastic structural change between an active open state and an inactive closed conformation. This conformational change of the MPD putatively acts as a molecular switch, facilitating a global reorientation of the extracellular domains in ADAM17 and regulating its shedding activity.
