Descripción general
Amyloid-β (Aβ) peptides are a major component of the senile plaques characteristic of the Alzheimer brain. It is a type- I transmembrane protein. The gene encoding amyloid-β is localized on human chromosome 21.
Aplicación
Human amyloid precursor protein β has been used as peptide standard.
Acciones bioquímicas o fisiológicas
The secreted amyloid precursor β (sAPPβ) is a proteolytic cleavage product of β amyloid precursor protein (APP). APP is cleaved by β-secretase into two fragments, sAPPβ and β-amyloid peptide (Aβ). The Aβ is a component of amyloid plaques, one of the major hallmarks of Alzheimer`s disease (AD), while the sAPPβ is thought to modulate neuronal function and cell survival. Mutation in APP found in Swedish familial AD pedigree increases the susceptibility of APP to β-secretase cleavage and the formation of Aβ and sAPPβ. In contrast, activation of protein kinase C (PKC) decreases the levels of sAPPβ. The trans-Golgi network (TGN) is the major site for β-secretase activity.

Studies of the molecular basis of Alzheimer's disease exemplify the increasingly blurred distinction between basic and applied biomedical research. The four genes so far implicated in familial Alzheimer's disease have each been shown to elevate brain levels of the self-aggregating
