Beta-amyloid (Ab) deposition in the brain is the hallmark of Alzheimer's Disease (AD).
To initiate Ab formation, beta-secretase cleaves APP at the N-terminus of Ab to release APPsb (~100kD soluble NT-fragment), and C99, a 12-kD CT membrane fragment.
Alternatively, alpha-secretase cleaves within the Ab to prevent the formation of Ab.
Cleavage by a-secretase produces a soluble N-terminal fragment, APPsa, and a 10-kD membrane C-terminal fragment, C83.
Both C99 and C83 can be further cleaved by gamma-secretase releasing Ab and a nonpathogenic p3 peptide, respectively
Recently TACE, a member of the ADAM family (A Disintegrin And Metalloprotease family) protease has been shown to play a central role in a regulated cleavage of human APP.
Inhibition of TACE affects both APP secretion and Ab formation in cultured cells (1).
Membrane-bound TNF-a, like APP, is transmembrane protein that can undergo TACE-mediated proteolysis to release the extracellular domain as soluble TNF-a.
TACE contain an autoinhibitory domain that must be removed for activity, a proteolytic domain, a disintegrin domain, a cysteine-rich domain, and a Transmembrane domain.
