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.
