Amyloid A Component
Description:
Amyloid A is a cell surface receptor and transmembrane precursor protein that is cleaved by secretases to form a number of peptides. Some of these peptides are secreted and can bind to the acetyltransferase complex APBB1/TIP60-promote transcriptional activation, while others form the protein basis of the amyloid plaques found in the brains of patients with Alzheimer disease. It also acts as a kinesin I membrane receptor, mediating the axonal transport of beta-secretase and presenilin 1. The protein is expressed in all fetal tissues, with highest levels in brain, kidney, heart and spleen. Multiple transcript variants encoding ten different isoforms have been found for the gene encoding Amyloid A protein. Mutations in the gene have been implicated in autosomal dominant Alzheimer disease and cerebroarterial amyloidosis (cerebral amyloid angiopathy).
