(beta‑site APP cleaving enzyme-1) is an aspartic protease and an integral membrane protein (1, 2). It is
the major beta secretase, and together with the gamma secretase, is responsible
for generating the amyloid beta peptide (A beta ) from the amyloid precursor
protein (APP) (3, 4). Because A beta is a major component of amyloid
plaques, BACE-1 has been implicated in the onset and/or progression of
Alzheimer's disease. High levels of BACE-1 activity are sufficient to
elicit neurodegeneration and neurological decline in vivo,
indicating that inhibiting BACE-1 may block not only A beta -dependent but
also A beta -independent pathogenic mechanisms (5). In addition to APP,
BACE-1 also cleaves APP-like proteins 1 and 2, the cell adhesion protein
P-selectin glycoprotein ligand-1 and beta -galactoside alpha 2,6-sialyltransferase,
implying that BACE-1 may have additional functions involving the
ectodomain shedding of membrane proteins (6 - 8).
