PSENEN / PEN-2

presenilin enhancer gamma secretase subunit

Presenilins, which are components of the gamma-secretase protein complex, are required for intramembranous processing of some type I transmembrane proteins, such as the Notch proteins and the beta-amyloid precursor protein. Signaling by Notch receptors mediates a wide range of developmental cell fates. Processing of the beta-amyloid precursor protein generates neurotoxic amyloid beta peptides, the major component of senile plaques associated with Alzheimer's disease. This gene encodes a protein that is required for Notch pathway signaling, and for the activity and accumulation of gamma-secretase. Mutations resulting in haploinsufficiency for this gene cause familial acne inversa-2 (ACNINV2). Alternative splicing results in multiple transcript variants.

Gene Name: presenilin enhancer gamma secretase subunit
Synonyms: PSENEN, Gamma-secretase subunit PEN-2, MSTP064, Presenilin enhancer protein 2, MDS033, PEN-2, PEN2
Target Sequences: NM_172341 NP_758844.1 Q9NZ42
