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.

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.

Emerging evidence from experimental and clinical research suggests that stress-related genes may play key roles in AD development. The fact that genome-wide association studies were not able to detect a contribution of such genes to AD indicates the possibility that

Amyloid precursor protein (APP) is expressed in many tissues in human, mice and in zebrafish. In zebrafish, there are two orthologues, Appa and Appb. Interestingly, some cellular processes associated with APP overlap with cilia-mediated functions. Whereas the localization of APP

The amyloid β-peptide (Aβ) is transported across the blood-brain barrier (BBB) by binding with the receptor for advanced glycation end products (RAGE). Previously, we demonstrated that the Aβ fraction 25-35 (Aβ25-35) increases RAGE expression in the rat hippocampus, likely contributing

The amyloid beta protein is deposited in the brains of patients with Alzheimer's disease but its pathogenic role is unknown. In culture, the amyloid beta protein was neurotrophic to undifferentiated hippocampal neurons at low concentrations and neurotoxic to mature neurons
