Cellular functions of gamma-secretase-related proteins [PDF]
, 2006 Amyloid-beta pepticle (A beta) is generated by gamma-secretase, a membrane protein complex with an unusual aspartyl protease activity consisting of the four components presenilin, nicastrin, APH-1 and PEN-2. Presenilin is considered the catalytic subunit

Tau is central in the genetic Alzheimer-frontotemporal dementia spectrum [PDF]
, 2005 In contrast to the common and genetically complex senile form of Alzheimer's disease (AD), the molecular genetic dissection of inherited presenile dementias has given important mechanistic insights into the pathogenesis of degenerative brain disease ...

Adult hippocampal neurogenesis occurs in the absence of Presenilin 1 and Presenilin 2 [PDF]
Scientific Reports, 2018 AbstractMutations in the presenilin genes (PS1 and PS2) are a major cause of familial-Alzheimer’s disease (FAD). Presenilins regulate neurogenesis in the developing brain, with loss of PS1 inducing aberrant premature differentiation of neural progenitor cells, and additional loss of PS2 exacerbating this effect.

Nuclear translocation and signalling of L1-CAM in human carcinoma cells requires ADAM10 and presenilin/gamma-secretase activity [PDF]
, 2009 L1-CAM (L1 cell-adhesion molecule), or more simply L1, plays an important role in the progression of human carcinoma. Overexpression promotes tumour-cell invasion and motility, growth in nude mice and tumour metastasis.

Presenilin promotes dietary copper uptake. [PDF]
PLoS ONE, 2013 Dietary copper is essential for multicellular organisms. Copper is redox active and required as a cofactor for enzymes such as the antioxidant Superoxide Dismutase 1 (SOD1). Copper dyshomeostasis has been implicated in Alzheimer's disease.

The role and therapeutic targeting of α-, β- and γ-secretase in Alzheimer's disease [PDF]
, 2015 Alzheimer's disease (AD) is the most common form of dementia in the elderly and its prevalence is set to increase rapidly in coming decades. However, there are as yet no available drugs that can halt or even stabilize disease progression. One of the main

Identification of caspases that cleave presenilin‐1 and presenilin‐2 [PDF]
FEBS Letters, 1999 Mutations in the presenilin (PS) genes PS1 and PS2 are involved in Alzheimer's disease (AD). Recently, apoptosis‐associated cleavage of PS proteins was identified. Here we demonstrate that PS1 as well as PS2 are substrates for different members of the caspase protein family. Remarkably, the caspases acting on PS1 could be subdivided in two groups.

Switched Aβ43 generation in familial Alzheimer’s disease with presenilin 1 mutation
Translational Psychiatry, 2021 Presenilin (PS) with a genetic mutation generates abundant β-amyloid protein (Aβ) 43. Senile plaques are formed by Aβ43 in the cerebral parenchyma together with Aβ42 at middle ages. These brains cause the early onset of Alzheimer’s disease (AD), which is

Calcium in the initiation, progression and as an effector of Alzheimer's disease pathology. [PDF]
, 2009 The cause(s) of sporadic Alzheimer's disease (sAD) are complex and currently poorly understood. They likely result from a combination of genetic, environmental, proteomic and lipidomic factors that crucially occur only in the aged brain.
