Catalytic activity:Broad endopeptidase specificity. Cleaves Glu-Val-Asn-Leu-|-Asp-Ala-Glu-Phe in the Swedish variant of Alzheimer's amyloid precursor protein. ,enzyme regulation:Inhibited by RTN3 and RTN4. ,Function:Responsible for the proteolytic processing of the amyloid precursor protein (APP) . Cleaves at the N-terminus of the A-beta peptide sequence , between residues 671 and 672 of APP , leads to the generation and extracellular release of beta-cleaved soluble APP , and a corresponding cell-associated C-terminal fragment which is later released by gamma-secretase. ,similarity:Belongs to the peptidase A1 family. ,subunit:Monomer. Interacts with GGA1 , GGA2 and GGA3. Interacts with RTN3 and RTN4. ,tissue specificity:Brain. ,
