Rabbit polyclonal to BACE2Accumulation of the amyloid-b (Ab) plaque in the cerebral cortex is a critical event in the pathogenesis of Alzheimer's disease. Ab peptide is generated by proteolytic cleavage of the b-amyloid protein precursor(APP) at b- and g-sites by proteases. The long-sought-secretase was recently identified by several groups independently and designated beta-site APP cleaving enzyme (BACE) and aspartyl protease 2 (Asp2) (1-4). BACE/Asp2 is a novel transmembrane aspartic protease and co-localizes with APP. A BACE homolog was recently cloned and designated BACE2, Asp1, DRAP (for Down Region Aspartic Protease), and memapsin 1 (4-9). BACE2 also cleaves APP at b-site and at a different site within Ab (8). BACE2 locates on chromosome 21q22.3, the so-called Down critical region, suggesting thatBACE2 and Ab may also contribute to the pathogenesis of Down syndrome (6,7). |
