Biochem/physiol Actions
Amyloid ?-Protein Fragment 25-35 (A?25-35) is involved in the pathogenesis of Alzheimer?s disease. Inhibitors of this transition may serve as a potential agent in managing Alzheimer?s disease. It is present in the subiculum and entorhinal cortex neurons of Alzheimer?s brain samples and inclusion-body myositis (IBM) muscle. It binds to receptors present in microglia and is capable of lipid membrane insertion. The functional domain sequence of A? comprising of sequence GSNKGAIIGLM elicits neurotrophic and neurotoxic effects. A?25-35 exhibits rapid aggregation and displays age dependant neurotoxicity.
General description
Amyloid ?-Protein Fragment 25-35 (A?25-35) is derived from the amyloid-? protein.amyloid-? protein, which is mapped to human chromosome 21q21. A?25-35 lacks the N-terminal domain and the metal binding site and is majorly generated by proteolytic cleavage of A?(1?40) peptides. It has a ?-sheet and ?-turn structure.
