Amyloid β-protein is neurotrophic and neurotoxic in vivo and in vitro in human and rat neuronal cell cultures. β-Amyloid peptides (amino acids 1-42 and 1-43) are the major constituents of senile plaques and neurofibrillary tangles that occur in the hippoc | [Definition]
ChEBI: Amyloid-beta polypeptide 40 is a beta-amyloid that is a 40 amino acid polypeptide of sequence Asp Ala Glu Phe Arg His Asp Ser Gly Tyr Glu Val His His Gln Lys Leu Val Phe Phe Ala Glu Asp Val Gly Ser Asn Lys Gly Ala Ile Ile Gly Leu Met Val Gly Gly Val Val. | [General Description]
Amyloid β Protein Fragment 1-40 (Aβ40) is derived from the amyloid-β protein (Aβ), which is mapped to human chromosome 21q21.3. Aβ40 is predominantly present in the vascular amyloid deposits. Aβ40 comprises of C-terminal membrane insertion domain. It shows structural transition from random coil to a α-helical structure in a water-micelle medium. | [Biological Activity]
amyloid β-peptide (1-40) (human), (c194h295n53o58s1), a peptide with the sequence h2n-daefrhdsgyevhhqklvffaedvgsnkgaiiglmvggvvia-oh, mw= 4329.8. amyloid beta (aβ or abeta) is a peptide of 36-43 amino acids that is processed from the amyloid precursor protein. while best known as a component of amyloid plaques in association with alzheimer's disease, evidence has been found that aβ is a highly multifunctional peptide with significant non-pathological activity(1). aβ is the main component of deposits found in the brains of patients with alzheimer's disease. brain aβ is elevated in patients with sporadic alzheimer’s disease. aβ is the main constituent of brain parenchymal and vascular amyloid, it contributes to cerebrovascular lesions and is neurotoxic(2). aβ protein is generated by successive action of the β and γ secretases. the γ secretase, which produces the c-terminal end of the aβ peptide, cleaves within the transmembrane region of app and can generate a number of isoforms of 36-43 amino acid residues in length. the most common isoforms are aβ40 and aβ42; the longer form is typically produced by cleavage that occurs in the endoplasmic reticulum, while the shorter form is produced by cleavage in the trans-golgi network(3).figure1 structure of amyloid β-peptide (1-40) (human) | [Biochem/physiol Actions]
Amyloid β-protein is neurotrophic and neurotoxic in vivo and in vitro in human and rat neuronal cell cultures. β-Amyloid peptides (amino acids 1-42 and 1-43) are the major constituents of senile plaques and neurofibrillary tangles that occur in the hippocampus, neocortex, and amygdala of patients with Alzheimer′s disease. | [storage]
