|Function||Regulator of gamma-secretase activity, which specifically activates the production of amyloid-beta protein (amyloid-beta protein 40 and amyloid-beta protein 42), without affecting the cleavage of other gamma-secretase targets such has Notch. The gamma-secretase complex is an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (amyloid-beta precursor protein). Specifically promotes the gamma-cleavage of APP CTF-alpha (also named APP-CTF) by the gamma-secretase complex to generate amyloid- beta, while it reduces the epsilon-cleavage of APP CTF-alpha, leading to a low production of AICD.|
|Cellular Location||Golgi apparatus, trans-Golgi network|
|Tissue Location||Widely expressed.|

Accumulation of neurotoxic amyloid-beta is a majorhallmark of Alzheimer disease (AD; MIM 104300). Formation ofamyloid-beta is catalyzed by gamma-secretase (see PSEN1; MIM104311), a protease with numerous substrates. PION, or GSAP,selectively increases amyloid-beta production through a mechanisminvolving its interaction with both gamma-secretase and itssubstrate, the amyloid-beta precursor protein (APP; MIM 104760)C-terminal fragment (APP-CTF) (He et al., 2010 [PubMed20811458]).
