Product Science Overview
Amyloid beta (A4) precursor protein (APP) is a transmembrane glycoprotein that plays a crucial role in the development of Alzheimer’s disease. The human recombinant version of this protein, produced in Human Embryonic Kidney (HEK) cells, is widely used in research to study its structure, function, and role in disease pathology.
The APP gene is located on chromosome 21 and encodes a protein that can be processed into several isoforms through alternative splicing . The full-length APP protein is approximately 100-140 kDa in size and consists of a large extracellular domain, a single transmembrane domain, and a short intracellular domain .
APP is involved in various physiological processes, including:
- Neurite Growth: APP functions as a cell surface receptor that promotes neurite outgrowth and neuronal adhesion .
- Synaptic Formation and Repair: It plays a role in synaptic formation and repair, contributing to the maintenance of synaptic plasticity .
- Iron Export: APP is involved in the export of iron from cells, which is crucial for maintaining cellular iron homeostasis .
APP undergoes proteolytic cleavage by enzymes known as secretases. The cleavage process involves:
The accumulation of Aβ peptides leads to the formation of amyloid plaques, a hallmark of Alzheimer’s disease. These plaques disrupt neuronal function and trigger a cascade of events that result in neurodegeneration . Mutations in the APP gene are associated with familial forms of Alzheimer’s disease and cerebral amyloid angiopathy .
Human recombinant APP produced in HEK cells is used extensively in research to:
- Study Protein Interactions: Investigate the interactions between APP and other proteins involved in Alzheimer’s disease.
- Drug Development: Screen potential therapeutic compounds that can modulate APP processing or prevent Aβ aggregation.
- Functional Studies: Explore the physiological roles of APP and its fragments in neuronal function and disease pathology .
