A disintegrin and metallopeptidase domain 17 (ADAM17) belongs to ADAM family of genes, which has a characteristic cysteine rich region called disintegrin and a metalloproteinase domain. This gene is located on chromosome 2, spans 55kb and has 19 exons. In adult humans, ADAM17 is expressed in multiple tissues such as, heart, muscle, kidney, placenta, pancreas, thymus, small intestine, ovaries, testes and prostate. In fetus, it is expressed in brain, lung, liver and kidney.
Acciones bioquímicas o fisiológicas
ADAMs (A disintegrin and metallopeptidases) are called ectodomain sheddases and ADAM17 is an angiotensin-converting enzyme 2 (ACE2) sheddase. It also processes and sheds multiple cell surface molecules such as, adhesion molecules and cytokines. It produces the soluble form of tumor necrosis factor α (TNF-α), along with the processing of I-CAM (cell adhesion molecule), V-CAM, IL-6R, L-selectin etc. These in turn play a role in development, regeneration and inflammation of the circulatory system. Polymorphism rs12692386 in ADAM17 gene is associated with an increased susceptibility to abdominal aortic aneurysm. This gene is also up-regulated in myocardial infarction patients, as well as in atherosclerosis patients. It also plays a role in the pathophysiology of ischemic strokes (IS). ADAM17 aids in tumor progression by facilitating tumor proliferation and invasion, as in the case of non-small cell lung cancer (NSCLC).
The untagged rh-TACE (TNF-alpha converting enzyme) is supplied as a lyophilized powder.
