Interaction between intrinsically disordered proteins Praja1 and α-synuclein on gold electrodes

The behavior of Praja1 (PJA1) interacting with alpha-synuclein (α-Syn) on a gold electrode was investigated using electrochemical methods, where both PJA1 and α-Syn are intrinsically disordered proteins. From the electrode reaction of ferricyanide ions added as probe, it was suggested that PJA1 interacts with α-Syn even when adsorbed on gold substrate and that the state of PJA1 on gold electrodes can be classified into four categories depending on the α-Syn concentration.
