Biology and pathophysiology of the amyloid precursor protein [PDF]
Molecular Neurodegeneration, 2011 The amyloid precursor protein (APP) plays a central role in the pathophysiology of Alzheimer's disease in large part due to the sequential proteolytic cleavages that result in the generation of β-amyloid peptides (Aβ).

Amyloid Precursor Protein (APP) and GABAergic Neurotransmission [PDF]
Cells, 2019 The amyloid precursor protein (APP) is the parent polypeptide from which amyloid-beta (Aβ) peptides, key etiological agents of Alzheimer’s disease (AD), are generated by sequential proteolytic processing involving β- and γ-secretases.

Amyloid Precursor Protein and Alzheimer's Disease. [PDF]
Int J Mol Sci, 2023 Alzheimer’s disease (AD) is one of the most common neurodegenerative disorders associated with age or inherited mutations. It is characterized by severe dementia in the late stages that affect memory, cognitive functions, and daily life overall. AD progression is linked to the accumulation of cytotoxic amyloid beta (Aβ) and hyperphosphorylated tau ...

Amyloid precursor protein and mitochondria. [PDF]
Curr Opin Neurobiol, 2023 Amyloid Precursor Protein (APP) processing to amyloid beta (Aβ) is a major hallmark of Alzheimer's disease (AD). The amyloid cascade hypothesis postulates that Aβ accumulation and aggregation causes AD, however many therapeutics targeting Aβ have failed recently. Decades of research describe metabolic deficits in AD.

Neuroprotective Secreted Amyloid Precursor Protein Acts by Disrupting Amyloid Precursor Protein Dimers [PDF]
Journal of Biological Chemistry, 2009 The amyloid precursor protein (APP) is implied both in cell growth and differentiation and in neurodegenerative processes in Alzheimer disease. Regulated proteolysis of APP generates biologically active fragments such as the neuroprotective secreted ectodomain sAPPalpha and the neurotoxic beta-amyloid peptide.

Binding of F-spondin to amyloid-β precursor protein: A candidate amyloid-β precursor protein ligand that modulates amyloid-β precursor protein cleavage [PDF]
Proceedings of the National Academy of Sciences, 2004 Amyloid-β precursor protein (APP), a type I membrane protein, is physiologically processed by α- or β-secretases that cleave APP N-terminal to the transmembrane region. Extracellular α-/β-cleavage of APP generates a large secreted N-terminal fragment, and a smaller cellular C-terminal fragment.

Heteromers of amyloid precursor protein in cerebrospinal fluid [PDF]
Molecular Neurodegeneration, 2015 Soluble fragments of the amyloid precursor protein (APP) generated by α- and β-secretases, sAPPα and sAPPβ, have been postulated as promising new cerebrospinal fluid (CSF) biomarkers for the clinical diagnosis of Alzheimer's disease (AD). However, the capacity of these soluble proteins to assemble has not been explored and could be relevant. Our aim is

AMYPdb: A database dedicated to amyloid precursor proteins [PDF]
BMC Bioinformatics, 2008 Abstract Background Misfolding and aggregation of proteins into ordered fibrillar structures is associated with a number of severe pathologies, including Alzheimer's disease, prion diseases, and type II diabetes. The rapid accumulation of knowledge about the sequences and structures of these proteins allows using of ...

Amyloid precursor protein and amyloid precursor-like protein 2 in cancer
Oncotarget, 2016 Amyloid precursor protein (APP) and its family members amyloid precursor-like protein 1 (APLP1) and amyloid precursor-like protein 2 (APLP2) are type 1 transmembrane glycoproteins that are highly conserved across species. The transcriptional regulation of APP and APLP2 is similar but not identical, and the cleavage of both proteins is regulated by ...

Intraneuronal compartments of the amyloid precursor protein [PDF]
The Journal of Neuroscience, 1993 The amyloid precursor protein (APP) is the parent molecule from which beta-amyloid protein is cleaved and deposits as amyloid fibrils in the senile plaques of Alzheimer's disease. Its primary structure resembles a receptor; however, no ligand has been identified. In growing hippocampal neurons APP is localized to growth cones.
