== Function ==
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 signaling|Notch receptor]], such that they either directly regulate [[gamma secretase]] activity or themselves are [[protease]] enzymes. Multiple alternatively spliced transcript variants have been identified for this gene, the full-length natures of only some have been determined.<ref>{{cite web | title = Entrez Gene: PSEN1 presenilin 1 (Alzheimer disease 3)| url = https://www.ncbi.nlm.nih.gov/gene?Db=gene&Cmd=ShowDetailView&TermToSearch=5663}}</ref>

=== Wnt signaling pathway ===
[[Wnt signaling pathway]] has been shown to be involved in several critical steps in embryogenesis and development. Presenilin 1 has been shown to form a complex with [[beta-catenin]], an important component in Wnt signaling, and stabilize beta-catenin.<ref name="Zhang_2009">{{cite journal | vauthors = Zhang C, Wu B, Beglopoulos V, Wines-Samuelson M, Zhang D, Dragatsis I, Südhof TC, Shen J | title = Presenilins are essential for regulating neurotransmitter release | journal = Nature | volume = 460 | issue = 7255 | pages = 632–6 | date = July 2009 | pmid = 19641596 | pmc = 2744588 | doi = 10.1038/nature08177 | bibcode = 2009Natur.460..632Z }}</ref> Mutant of presenilin-1 that reduces the ability to stabilize beta-catenin complex leads to hyperactive degradation of beta-catenin in the brains of transgenic mice.<ref name="Zhang_2009"/>

=== Beta-amyloid production === Transgenic mice that over-expressed mutant presenilin-1 show an increase of beta-amyloid-42(43) in the brain, which suggest presenilin-1 plays an important role in beta-amyloid regulation and can be highly related to Alzheimer's disease.<ref name="pmid8878479">{{cite journal | vauthors = Duff K, Eckman C, Zehr C, Yu X, Prada CM, Perez-tur J, Hutton M, Buee L, Harigaya Y, Yager D, Morgan D, Gordon MN, Holcomb L, Refolo L, Zenk B, Hardy J, Younkin S | title = Increased amyloid-beta42(43) in brains of mice expressing mutant presenilin 1 | journal = Nature | volume = 383 | issue = 6602 | pages = 710–3 | date = October 1996 | pmid = 8878479 | doi = 10.1038/383710a0 | bibcode = 1996Natur.383..710D | s2cid = 4339658 }}</ref> Further study conducted in neuronal cultures derived from presenilin-1 deficient mouse embryos showed that cleavage by alpha- and beta- secretase was still normal without the presence of presenilin-1.

=== Alzheimer's disease ===
[[Alzheimer's disease]] (AD) patients with an inherited form of the disease may carry mutations in the presenilin proteins (PSEN1; [[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). These mutations result in early-onset Alzheimer's Disease, which is a rare form of the disease. These rare genetic variants are autosomal dominant.<ref name="pmid22908189">{{cite journal|author-link2=Yaakov Stern | vauthors = Mayeux R, Stern Y | title = Epidemiology of Alzheimer disease | journal = Cold Spring Harbor Perspectives in Medicine | volume = 2 | issue = 8 | article-number = a006239| year = 2012 | pmid = 22908189 | pmc = 3405821 | doi = 10.1101/cshperspect.a006239 }}</ref>
=== Cancer ===
In addition to its role in Alzheimer's disease, presenilin-1 also found to be important in cancer. A study of broad range gene expression was conducted on human [[melanoma]].
