PSENEN
PSENEN (Gamma-secretase subunit PEN-2) is a gene. The public catalogues list it as a drug target, and an approved or late-stage drug is recorded against it. Tied to Desmoid tumour. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
Essential subunit of the gamma-secretase complex, an endoprotease complex that catalyses the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (amyloid-beta precursor protein). The gamma-secretase complex plays a role in Notch and Wnt signalling cascades and regulation of downstream processes via its role in processing key regulatory proteins, and by regulating cytosolic CTNNB1 levels. PSENEN modulates both endoproteolysis of presenilin and gamma-secretase activity. Besides its role in gamma-secretase complex, acts as a regulator of AMP-activated protein kinase (AMPK) activity in response to calorie restriction: binds metformin, an antidiabetic drug, promoting association with ATP6AP1, a subunit of the V-ATPase complex, leading to V-ATPase complex inhibition on lysosomes and AMPK activation via the AXIN1-STK11/LKB1 axis. Location: Endoplasmic reticulum membrane; Golgi apparatus, Golgi stack membrane; Cell membrane; Membrane (UniProt). Locus 19q13.12 (HGNC).
