The BACE2 (Beta-Secretase 2) gene encodes an aspartyl protease that can cleave amyloid precursor protein (APP). BACE2 shares 64% sequence homology with BACE1, the primary beta-secretase involved in amyloid-beta production. Unlike BACE1, BACE2 can also cleave APP at alternative sites, potentially generating non-amyloidogenic fragments. BACE2 is expressed in various tissues including brain, pancreas, and heart. While less studied than BACE1, BACE2 has been implicated in Alzheimer's disease pathogenesis and represents an alternative therapeutic target.
Beta-site APP-cleaving enzyme 2 (BACE2) is an aspartyl protease that cleaves amyloid precursor protein (APP). It is expressed in the brain and periphery and has been studied as a potential therapeutic target for Alzheimer's disease.
BACE2 is a member of the aspartyl protease family and shares 64% sequence homology with BACE1. Like BACE1, BACE2 can cleave APP at the β-secretase site to initiate amyloidogenic processing. However, BACE2 also has α-secretase-like activity and can cleave APP within the Aβ domain, potentially generating non-amyloidogenic fragments. BACE2 is expressed in various tissues including brain, pancreas, and heart. Its physiological functions are less well understood than BACE1, but it may play roles in pancreatic β-cell function and adipocyte biology.
Alzheimer's Disease; Down Syndrome; Diabetes Mellitus
BACE2 is expressed in many tissues including brain, pancreas, kidney, and heart. In the brain, it is expressed in neurons and glial cells, though generally at lower levels than BACE1.
