Genes affected

BACE1 (HGNC:933): (beta-secretase 1) This gene encodes a member of the peptidase A1 family of aspartic proteases. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed to generate the mature protease. This transmembrane protease catalyzes the first step in the formation of amyloid beta peptide from amyloid precursor protein. Amyloid beta peptides are the main constituent of amyloid beta plaques, which accumulate in the brains of human Alzheimer's disease patients. [provided by RefSeq, Nov 2015]

BACE1-AS (HGNC:37125): (BACE1 antisense RNA) This gene encodes an unspliced long non-coding RNA transcribed from the opposite strand to BACE1. The encoded transcript is thought to form an RNA duplex with BACE1 mRNA thereby regulating its expression and is also thought to promote post-transcriptional feed-forward regulation of BACE1. This may lead to increased levels of beta amyloid and increased senile plaque deposition, and therefore may play a role in the pathophysiology of Alzheimer's disease. [provided by RefSeq, Jan 2015]
