Application

Amyloid β-Protein Fragment 35-25 has been used as a control peptide for Aβ-induced apoptosis to study the role of hepcidin overexpression in astrocytes against amyloid-β induced brain damage in mice.

Biochem/physiol Actions

Proteolytic processing of amyloid β precursor protein (APP) forms the β amyloid protein (Aβ) as part of the brain amyloid plaques which are the key biomarkers in Alzheimer′s disease. APP is known to be associated with neurogenesis, synapse formation, axonal transport, neuronal migration and neurite outgrowth. It is also related to mitochondria-associated endoplasmic reticulum membranes (MAMs) activity, antimicrobial protection, cholesterol, and iron homeostasis. Amyloid β-Protein Fragment 35-25 is an inactive control.

General description

Amyloid β precursor protein (APP) is a type-1 transmembrane protein. APP is expressed widely and mainly found in the synapses and neurons. The APP gene is mapped to human chromosome 21q21.3.
