Function

BACE1_HUMAN 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.[1] [2]

Publication Abstract from PubMed

The structure-based design, synthesis, and X-ray structure of protein-ligand complexes of exceptionally potent and selective beta-secretase inhibitors are described. The inhibitors are designed specifically to interact with S(1)' active site residues to provide selectivity over memapsin 1 and cathepsin D. Inhibitor 5 has exhibited exceedingly potent inhibitory activity (K(i) = 17 pM) and high selectivity over BACE 2 (>7000-fold) and cathepsin D (>250000-fold). A protein-ligand crystal structure revealed important molecular insight into these selectivities. These interactions may serve as an important guide to design selectivity over the physiologically important aspartic acid proteases.
