PSEN2 - presenilin 2 Gene
Also Known as AD4; PS2; AD3L; STM2; CMD1V
Species: Homo sapiens
About PSEN2
This gene has 37 transcripts (splice variants), 205 orthologues, 1 paralogue and is associated with 4 phenotypes. Ubiquitous expression in testis (RPKM 4.6), prostate (RPKM 4.4) and 25 other tissues.
Summary
Alzheimer's disease (AD) patients with an inherited form of the disease carry mutations in the presenilin proteins (PSEN1 or PSEN2) or the amyloid precursor protein (APP). These disease-linked mutations result in increased production of the longer form of amyloid-beta (main component of amyloid deposits found in AD brains). Presenilins are postulated to regulate APP processing through their effects on gamma-secretase, an enzyme that cleaves APP. Also, it is thought that the presenilins are involved in the cleavage of the Notch receptor such that, they either directly regulate gamma-secretase activity, or themselves act are protease Enzymes. Two alternatively spliced transcript variants encoding different isoforms of PSEN2 have been identified. [provided by RefSeq, Jul 2008]
