|Fluorescent sensors for Cu(II) have been recently developed using peptide motifs from metal binding proteins. This has proved to be a better approach than using chelator motifs since the proteins metal selectivity is maintained. Several proteins associated with neurodegenerative disorders, such as prion protein (PrP), amyloid-Î² (AÎ²) and Î±-synuclein all possess copper- binding sequences in their N-terminus. Here we present that fluorescent dye conjugated N-terminal AÎ² peptide could potentially be developed as an excellent Cu(II) biosensor. The feasibility for in vivo applications such as detecting the copper release in synapse has been explored by determining the rate of binding of copper ions to AÎ² 1-16 . It was also found by simulation and experiment that the peptide sensor can efficiently compete with copper-binding amino acids, such as glycine and glutamate, rich in the synaptic clefts of neurons.|
