BACE2 - beta-secretase 2 Gene
Also Known as ASP1; BAE2; DRAP; AEPLC; ALP56; ASP21; CDA13; CEAP1
Species: Homo sapiens
About BACE2
This gene has 10 transcripts (splice variants), 215 orthologues and 9 paralogues. Ubiquitous expression in stomach (RPKM 12.5), gall bladder (RPKM 11.8) and 23 other tissues.
Summary
This gene encodes an integral membrane glycoprotein that functions as an aspartic protease. The encoded protein cleaves amyloid precursor protein into amyloid beta peptide, which is a critical step in the etiology of Alzheimer's disease and Down syndrome. The protein precursor is further processed into an active mature peptide. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]
