Using the PEP-scan approach, we have identified the binding site of PP2Ac to LRRK2, a protein associated with Parkinson's disease. We also have identified the binding site of LRRK2 to PP2Ac, referred to as mirror peptide. All isolated fragments are predicted to be solvent-accessible and are compatible with contributing to LRRK2/PP2Ac interaction except for peptide M2. The In vitro competition experiment demonstrated that peptide P3 and M1 effectively compete PP2A/LRRK2 interaction. Both appear to have propensity to adopt helical conformation. These newly generated peptides can be tools to investigate the role of PP2A/LRRK2 interaction under both physiological and pathological conditions.
