Amyloid Precursor Protein Proteins

Protein Information

Amyloid Precursor Protein (APP) or Amyloid beta precursor protein functions as a cell surface kinesin I membrane receptor, mediating the axonal transport of beta-secretase and presenilin 1. APP is important for neurite growth, neuronal adhesion and axonogenesis. APP is a 100-140 kDa transmembrane glycoprotein that exists as several isoforms resulting from alternative splicing. Proteolytic cleavage of APP by beta- and gamma-secretases results in the generation of beta amyloid, which is the primary component of senile plaques. Senile plaques are one of the major histopathologic features of Alzheimer's disease. Abnormal regulation and processing of APP also plays a role in Down's syndrome, early onset familial Alzheimer's disease, and cerebral hemorrhage.
