Beta-secretase 1 Overview

Beta-secretase 1 (BACE1) is a transmembrane aspartic protease that initiates the production of amyloid-beta peptides by cleaving amyloid precursor protein (APP). This cleavage is a critical step in the pathogenesis of Alzheimer's disease. BACE1 also plays a role in myelination, particularly in peripheral nerves. It is considered a therapeutic target for Alzheimer's disease, with inhibitors aimed at reducing amyloid-beta production.

Mechanism of Action

Inhibition of BACE1 prevents the formation of amyloid-beta peptides.

Biological Functions

Amyloid precursor protein (APP) cleavage
Amyloid-beta peptide production
Myelination
Hydrolyzing peptide bonds

Disease Associations

Alzheimer's Disease
Osteoarthritis
Shoulder lesion

Safety Considerations

  • Potential for cognitive side effects due to disruption of normal BACE1 function, such as myelination.
  • Off-target effects due to BACE1's activity on other substrates.

Associated Biomarkers

Biomarker
BACE1 levels in cerebrospinal fluid (CSF)
