(A) Immunoprecipitated (IP) FLAG-PARIS interacts with MYC-Parkin, but not MYC-XIAP or the PARIS homologue, V5-ZNF398 (lane 6), n = 3.
(B) GST-pull down assay between parkin and PARIS indicates a robust interaction between parkin and PARIS, n = 4.
(C) Immunoprecipitated FLAG-PARIS interacts with WT Parkin and Parkin mutants (C431F, G430D, R275W, Q311X) in SH-SY5Y cells. Lower panel, relative binding, data = mean ± S.E.M., n = 3, *p < 0.05, Student’s t-test.
(D) Immunoblot (IB) shows that Parkin and PARIS co-immunoprecipitate in human striatum, n = 3.
(E) Parkin and PARIS co-immunoprecipitate from WT mouse ventral midbrain, but not parkin KO ventral midbrain, n = 3.
