γ-Secretase is a proteolytic complex whose substrates include Notch, β-amyloid precursor protein (APP), and several other type I transmembrane proteins. Presenilin (PS) and nicastrin are known components of this high-molecular-weight complex, and recent ...

P2Y2 Nucleotide Receptors Enhance α-Secretase-dependent Amyloid Precursor Protein Processing [PDF]
The amyloid precursor protein (APP) is proteolytically processed by beta- and gamma-secretases to release amyloid beta, the main component in senile plaques found in the brains of patients with Alzheimer disease. Alternatively, APP can be cleaved within the amyloid beta domain by alpha-secretase releasing the non-amyloidogenic product sAPP alpha, which

The competitive ectodomain shedding of amyloid-β precursor protein (APP) by α-secretase and β-secretase, and the subsequent regulated intramembrane proteolysis by γ-secretase are the key processes in amyloid-β peptides (Aβ) generation.

Emerging structures and dynamic mechanisms of γ-secretase for Alzheimer’s disease
γ-Secretase, called “the proteasome of the membrane,” is a membrane-embedded protease complex that cleaves 150+ peptide substrates with central roles in biology and medicine, including amyloid precursor protein and the Notch family of cell-surface ...

The resveratrol trimer miyabenol C inhibits β-secretase activity and β-amyloid generation.
Accumulation and deposition of amyloid-β peptide (Aβ) in the brain is a primary cause of the pathogenesis of Alzheimer's disease (AD). Aβ is generated from amyloid-β precursor protein (APP) through sequential cleavages first by β-secretase and then by γ ...

Presenilin 2 is the predominant γ-secretase in microglia and modulates cytokine release. [PDF]
Presenilin 1 (PS1) and Presenilin 2 (PS2) are the enzymatic component of the γ-secretase complex that cleaves amyloid precursor protein (APP) to release amyloid beta (Aβ) peptide.

β‐secretase‐cleaved amyloid precursor protein in Alzheimer brain: a morphologic study [PDF]
Abstractβ‐amyloid (Aβ) is the main constituent of senile plaques seen in Alzheimer's disease. Aβ is derived from the amyloid precursor protein (APP) via proteolytic cleavage by proteases β‐ and β‐secretase. In this study, we examined content and localization of β‐secretase‐cleaved APP (β‐sAPP) in brain tissue sections from the frontal, temporal and ...

Regulation of amyloid precursor protein processing by serotonin signaling. [PDF]
Proteolytic processing of the amyloid precursor protein (APP) by the β- and γ-secretases releases the amyloid-β peptide (Aβ), which deposits in senile plaques and contributes to the etiology of Alzheimer's disease (AD). The α-secretase cleaves APP in the

-Secretase-Regulated Signaling Mechanisms: Notch and Amyloid Precursor Protein [PDF]
In Drosophila, Notch mutations lost a lateral signaling ability and produced a neurogenic phenotype, where cells destined to become epidermis switch fate and give rise to neural tissue (Artavanis-Tsakonas et al. 1995; Lewis 1998). Therefore, when Notch signaling was disrupted, too many neurons were generated.

Cellular prion protein regulates β-secretase cleavage of the Alzheimer's amyloid precursor protein [PDF]
Proteolytic processing of the amyloid precursor protein (APP) by β-secretase, β-site APP cleaving enzyme (BACE1), is the initial step in the production of the amyloid β (Aβ) peptide, which is involved in the pathogenesis of Alzheimer's disease.
