[[http://www.uniprot.org/uniprot/PSN1_HUMAN PSN1_HUMAN]] Defects in PSEN1 are a cause of Alzheimer disease type 3 (AD3) [MIM:[http://omim.org/entry/607822 607822]]. AD3 is a familial early-onset form of Alzheimer disease. Alzheimer disease is a neurodegenerative disorder characterized by progressive dementia, loss of cognitive abilities, and deposition of fibrillar amyloid proteins as intraneuronal neurofibrillary tangles, extracellular amyloid plaques and vascular amyloid deposits. The major constituent of these plaques is the neurotoxic amyloid-beta-APP 40-42 peptide (s), derived proteolytically from the transmembrane precursor protein APP by sequential secretase processing. The cytotoxic C-terminal fragments (CTFs) and the caspase-cleaved products such as C31 derived from APP, are also implicated in neuronal death.<ref>PMID:12058025</ref><ref>PMID:7596406</ref><ref>PMID:8634711</ref><ref>PMID:8634712</ref><ref>PMID:7651536</ref><ref>PMID:7550356</ref><ref>PMID:8733303</ref><ref>PMID:9225696</ref><ref>PMID:9298817</ref><ref>PMID:9172170</ref><ref>PMID:9833068</ref><ref>PMID:9384602</ref><ref>PMID:9521423</ref><ref>PMID:10200054</ref><ref>PMID:9719376</ref><ref>PMID:9507958</ref><ref>PMID:9831473</ref><ref>PMID:10441572</ref><ref>PMID:10090481</ref><ref>PMID:10447269</ref><ref>PMID:10533070</ref><ref>PMID:10025789</ref><ref>PMID:10208579</ref><ref>PMID:10439444</ref><ref>PMID:10631141</ref><ref>PMID:10644793</ref><ref>PMID:11027672</ref>[:]<ref>PMID:11710891</ref><ref>PMID:11920851</ref><ref>PMID:12048239</ref><ref>PMID:12484344</ref><ref>PMID:12493737</ref> Defects in PSEN1 are a cause of frontotemporal dementia (FTD) [MIM:[http://omim.org/entry/600274 600274]].

[[http://www.uniprot.org/uniprot/PSN1_HUMAN PSN1_HUMAN]] Probable catalytic subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta-amyloid precursor protein). Requires the other members of the gamma-secretase complex to have a protease activity. May play a role in intracellular signaling and gene expression or in linking chromatin to the nuclear membrane. Stimulates cell-cell adhesion though its association with the E-cadherin/catenin complex. Under conditions of apoptosis or calcium influx, cleaves E-cadherin promoting the disassembly of the E-cadherin/catenin complex and increasing the pool of cytoplasmic beta-catenin, thus negatively regulating Wnt signaling. May also play a role in hematopoiesis.<ref>PMID:10545183</ref><ref>PMID:10593990</ref><ref>PMID:10206644</ref><ref>PMID:10899933</ref><ref>PMID:10811883</ref><ref>PMID:11226248</ref><ref>PMID:15341515</ref><ref>PMID:16305624</ref>
