TACE Blocking Peptide

This gene encodes a member of the ADAM (a disintegrin and metalloprotease domain) family. Members of this family are membrane-anchored proteins structurally related to snake venom disintegrins, and have been implicated in a variety of biologic processes involving cell-cell and cell-matrix interactions, including fertilization, muscle development, and neurogenesis. The protein encoded by this gene functions as a tumor necrosis factor-alpha converting enzyme; binds mitotic arrest deficient 2 protein; and also plays a prominent role in the activation of the Notch signaling pathway.

TACE: a type I membrane protein with disintegrin and metalloprotease activity. An ubiquitously expressed ectoenzyme of peptidase family M12B. Must be membrane anchored to cleave the different substrates. The cytoplasmic domain is not required for the this activity. Possesses a narrow endopeptidase specificity. Cleaves Pro-Leu-Ala-Gln-Ala-|-Val-Arg-Ser-Ser-Ser in the membrane-bound, 26-kDa form of tumor necrosis factor alpha (TNF-alpha) to its mature soluble form. 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, and the amyloid precursor protein. Also involved in the activation of Notch pathway. Binds 1 zinc ion per subunit. Two splice variant isoforms have been described.
