evolutionary trace analysis identifies group-specific residues in the ligand binding sites of BACE1, EC 3.4.23.46, and BACE2.The residues are Pro70, Ile110, Ile126, andAsn233 of BACE1 substituting Lys86, Leu126, Leu142, and Leu246 of BACE2, respectively.These group-specific residues would be the reason for cleavage site selectivity in BACE1 and BACE2 biological function

BACE2 mRNA levels are downregulated at 6, 12, and 24 h exposure to 0.01 mM AlCl3 and 0.002 mM amyloid beta peptide
BACE2 mRNA levels are significantly increased after 1 and 3 h exposure to 0.01 mM AlCl3 and 0.002 mM amyloid beta peptide
neither treatment with 0.002 mM of the Abeta(25-35) fragment nor with 0.01 mM AlCl3 alone influences BACE2 gene mRNA after 24 h

medicine
pharmacology
the enzyme is a potential target for development of inhibitors in Alzheimer's disease therapy and treatment of Down syndrome
drug development
-
therapeutic interventions that potentiate BACE2 may prevent AlzheimerĀ’s disease
medicine
-
samples from frontal cortex of both Alzheimer's disease-affected individuals and age-matched controls show substantial total amounts of BACE2 protein and enzymatic activity. BACE2 activity does not change significantly in the brain of patients with Alzheimer's disease, and is not related to amyloid beta-peptide concentration
