Amyloid precursor protein trafficking, processing, and function.
Intracellular trafficking and proteolytic processing of amyloid precursor protein (APP) have been the focus of numerous investigations over the past two decades. APP is the precursor to the amyloid beta-protein (Abeta), the 38-43-amino acid residue peptide that is at the heart of the amyloid cascade hypothesis of Alzheimer disease (AD). Tremendous progress has been made since the initial identi...
متن کاملPhorbol Esters Affect Multiple Steps in 3,-Amyloid Precursor Protein Trafficking and Amyloid 0-Protein Production
Background: Amyloid ,3-protein (A,B), the major constituent of amyloid deposits found in Alzheimer's disease, is derived from the (3-amyloid precursor protein (O3PP). Constitutive proteolysis by a-secretase and secretion of soluble ,BPP (f3PPJ) are stimulated by protein kinase C (PKC) activation, whereas AP3 production and release are inhibited. The cellular mechanism that underlies the PKC-med...
متن کاملBinding of F-spondin to amyloid- precursor protein: A candidate amyloid- precursor protein ligand that modulates amyloid- precursor protein cleavage
Amyloidprecursor protein (APP), a type I membrane protein, is physiologically processed by or -secretases that cleave APP N-terminal to the transmembrane region. Extracellular -cleavage of APP generates a large secreted N-terminal fragment, and a smaller cellular C-terminal fragment. Subsequent -secretase cleavage in the transmembrane region of the C-terminal fragment induces secretion of small...
