LINGO-1 promotes lysosomal degradation of amyloid-β protein precursor
Sequential proteolytic cleavages of amyloid-β protein precursor (AβPP) by β-secretase and γ-secretase generate amyloid β (Aβ) peptides, which are thought to contribute to Alzheimer's disease (AD). Much of this processing occurs in endosomes following endocytosis of AβPP from the plasma membrane. However, this pathogenic mode of processing AβPP may occur in competition with lysosomal degradation...
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...
متن کاملHeterogeneous Association of Alzheimer’s Disease-Linked Amyloid-β and Amyloid-β Protein Precursor with Synapses
Alzheimer's disease (AD) is increasingly viewed as a disease of synapses. Loss of synapses correlates better with cognitive decline than amyloid plaques and neurofibrillary tangles, the hallmark neuropathological lesions of AD. Soluble forms of amyloid-β (Aβ) have emerged as mediators of synapse dysfunction. Aβ binds to, accumulates, and aggregates in synapses. However, the anatomical and neuro...
متن کاملAmyloid precursor protein mutation E682K at the alternative β-secretase cleavage β′-site increases Aβ generation†
BACE1 cleaves the amyloid precursor protein (APP) at the β-cleavage site (Met(671) -Asp(672) ) to initiate the generation of amyloid peptide Aβ. BACE1 is also known to cleave APP at a much less well-characterized β'-cleavage site (Tyr(681) -Glu(682) ). We describe here the identification of a novel APP mutation E682K located at this β'-site in an early onset Alzheimer's disease (AD) case. Funct...
