TNF-α converting enzyme (TACE) is a multidomain, membrane-anchored protein that includes a Zn-dependent protease domain. It releases the soluble form of cytokine tumor necrosis factor-α (TNF-α) from its membrane-bound precursor. TACE is a metalloprotease containing a catalytic glutamic acid, Glu-406...
