BACE-1 Antibody (137612)

Western blot shows lysates of human brain (Alzheimer's disease hippocampus) tissue. PVDF Membrane was probed with 2 µg/mL of Mouse Anti-Human/Mouse BACE‑1 Ectodomain Monoclonal Antibody (Catalog # MAB931) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). Specific bands were detected for BACE‑1 at approximately 60 and 70 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background

BACE-1 (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).
