Beta-secretase 1 precursor (EC 3.4.23.46) (Beta-site APP cleaving enzyme 1) (Beta-site amyloid precursor protein cleaving enzyme 1) (Membrane-associated aspartic protease 2) (Memapsin-2) (Aspartyl protease 2) (Asp 2) (ASP2); 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 (501 aa)
