STRING analysis reveals protein interaction networks of the proteins DJ-1 (PARK7) (A), PINK1 (B) and PARKIN (PARK2) (C) with other proteins. The interaction network was created with STRING (Search Tool for the Retrieval of Interacting Genes/Proteins) database version 10.5. A high confidence cutoff of 0.7 was implemented in this work. In the resulting protein association network, proteins are presented as nodes which are connected by lines whose thickness represents the confidence level (0.7–0.9).
