Constitutive and regulated α-secretase cleavage of Alzheimer’s amyloid precursor protein by a disintegrin metalloprotease

1999

Amyloid β peptide (Aβ), the principal proteinaceous component of amyloid plaques in brains of Alzheimer’s disease patients, is derived by proteolytic cleavage of the amyloid precursor protein (APP). Proteolytic cleavage of APP by a putative α-secretase within the Aβ sequence precludes the formation of the amyloidogenic peptides and leads to the release of soluble APPsα into the medium. By overexpression ofa disintegrinandmetalloprotease (ADAM), classified as ADAM 10, in HEK 293 cells, basal and protein kinase C-stimulated α-secretase activity was increased severalfold. The proteolytically activated form of ADAM 10 was localized by cell surface biotinylation in the plasma membrane, but the m…

Regulation of the alpha-secretase ADAM10 by its prodomain and proprotein convertases.

2001

SPECIFIC AIMSTo identify the proprotein convertases responsible for maturation of the α-secretase ADAM10, we investigated the influence of PC7 and furin on ADAM10 processing and the resulting effect on amyloid precursor protein cleavage. We also examined the functional role of the ADAM10 prodomain by coexpression of a prodomain-deleted ADAM10 mutant together with its prodomain in trans.PRINCIPAL FINDINGS1. ADAM10 is proteolytically processed by PC7 and furinThe disintegrin metalloproteinase ADAM10 possesses α-secretase activity as well as a potential proprotein convertase recognition sequence (RKKR) after its prodomain. By amino-terminal sequencing of ADAM10 purified from bovine kidney plas…
