Anti-ADAM 17 Antibody

NA.41

ADAM17, also known as TNF-alpha Convertase, or TACE, was first cloned from human epithelial cells. Tumor-necrosis factor alpha is a proinflammatory cytokine and contributes to a variety of inflammatory disease responses and programmed cell death. TNF-alpha is synthesized as a 26 kDa Type II membrane-bound precursor that is cleaved by a convertase to generate secreted 17K mature TNF-alpha. TNF-alpha converting enzyme (TACE) protein was recently purified and the human and mouse TACE cDNAs were cloned by several groups separately (1-3). The ADAM proteins are structurally similar, with a signal sequence, metalloprotease domain (inactive in some ADAMs), disintegrin domain, cystein rich domain, EGF like repeat, type I transmembrane, and a cytoplasmic domain. A member of the metalloproteinase family containing disintegrin like domains (ADAMs), ADAM17 is known to process the TNF alpha trimer from the membrane attached precursor to the soluble form. ADAM17 contains the canonical HExxHxxxxxH zinc metallo-proteinase motif, and has been shown to be proteolytically active, cleaving TNF precursor as well as TNF p75 receptor, myeloid precursor protein, amyloid plaque protein, L selectin and TGF alpha, making ADAM17 a "sheddase". Reports have shown that ADAM17 expression in human breast tumor samples is an indicator of poor prognosis.

TACE is a membrane-bound metallo-proteinase-disintegrin. ADAM 17 also processes other cell surface proteins, including TNF receptor, TGF alpha, the L-selectin adhesion molecule, and alpha-cleavage of amyloid protein precursor (APP) (4,5). ADAM 17 mRNA is expressed in a variety of human and murine tissues.

Raised against a peptide corresponding to amino acids 807-823 of human TACE (1,2). This sequence differs from those of mouse and rat TACE by one amino acid.(3).
