Presenilins Upregulate Functional K+Channel Currents in Mammalian Cells
Mutations in presenilin 1 (PS-1) and presenilin 2 (PS-2) have been linked to early onset, autosomal dominant Alzheimer's disease. Neither the normal function(s) of the presenilins nor their role(s) in mediating the devastating neurological and ...

Calcium in the initiation, progression and as an effector of Alzheimer's disease pathology. [PDF]
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.

Background Presenilin proteins are part of a complex of proteins that can cleave many type I transmembrane proteins, including Notch Receptors and the Amyloid Precursor Protein, in the middle of the transmembrane domain.

The Nicastrin ectodomain adopts a highly thermostable structure [PDF]
Nicastrin is a type I transmembrane glycoprotein, which is part of the high molecular weight gamma-secretase complex. gamma-Secretase is one of the key players associated with the generation of Alzheimer's disease pathology, since it liberates the ...

Comparison of Presenilin 1 and Presenilin 2 γ-Secretase Activities Using a Yeast Reconstitution System [PDF]
γ-Secretase is composed of at least four proteins, presenilin (PS), nicastrin (NCT), Aph1, and Pen2. PS is the catalytic subunit of the γ-secretase complex, having aspartic protease activity. PS has two homologs, namely, PS1 and PS2. To compare the activity of these complexes containing different PSs, we reconstituted them in yeast, which lacks γ ...

Cholestenoic acid, an endogenous cholesterol metabolite, is a potent γ-secretase modulator. [PDF]
BackgroundAmyloid-β (Aβ) 42 has been implicated as the initiating molecule in the pathogenesis of Alzheimer's disease (AD); thus, therapeutic strategies that target Aβ42 are of great interest.

miRNA-based rapid differentiation of purified neurons from hPSCs advancestowards quick screening for neuronal disease phenotypes in vitro [PDF]
Obtaining differentiated cells with high physiological functions by an efficient, but simple and rapid differentiation method is crucial for modeling neuronal diseases in vitro using human pluripotent stem cells (hPSCs).

Identification of caspases that cleave presenilin‐1 and presenilin‐2 [PDF]
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.
