Description : This peptide is the C-terminal fragment of amyloid precursor protein (APP) also known as C31. It is intracellularly generated by proteolytic cleavage of APP by caspases-8 and -9. C31 had a proapoptotic and a cytotoxic effect on neuronal cells and was shown to be present in brains of Alzheimer's disease (AD) patients. In cultured cells caspase cleavage of APP was induced by amyloid beta-protein and the subsequent generation of C31 contributed to the apoptotic cell death associated with amyloid beta-protein. Amyloid precursor binding protein BP1 (APP-BP1) a cell cycle protein which is increased in AD brain was demonstrated to bind to the C31 region of APP and to mediate APP-induced apoptosis.
