From the TGN, APP can be transported in TGN-derived secretory vesicles to the cell surface where it is either cleaved by alpha-secretase to produce a soluble molecule, sAPPalpha [37], or re-internalized via an endosomal/ lysosomal degradation pathway [38,39] PubMed:21214928
Cleavage of APP by alpha-secretase precludes Abeta generation as the cleavage site is within the Abeta domain (at the Lys16- Leu17 bond), and releases a large soluble ectodomain of APP called sAPPalpha PubMed:21214928
Manipulation of ADAM17 can alter alpha-cleavage of APP and Abeta generation, with regulated alpha-cleavage abolished in ADAM17-deficient cells, suggesting that ADAM17 is likely the alpha-secretase responsible for regulated APP cleavage [47] PubMed:21214928
APP can also be cleaved by alpha-secretase to form a soluble or secreted APP ectodomain (sAPP-alpha) that has been shown to be mostly neuro-protective PubMed:22122372
As APP was found to be constitutively cleaved at the alpha-site to yield sAPP-alpha (Esch et al. 1990), three members of the a disintegrin and metalloproteinase (ADAMs), ADAM-10,ADAM-17 and ADAM-9 have been proposed as the alpha-secretase (Buxbaum et al. 1998; Koike et al. 1999;Lammich et al. 1999) PubMed:22122372
