SARM1 promotes TRAF6-mediated ubiquitination of PINK1. (A) Ubiquitination of PINK1 by TRAF6 in cells. Cell lysates from SH-SY5Y cells transfected with PINK1-HA and Flag-ubiquitin (Ub) along with TRAF2-Myc or TRAF6-Myc were immunoprecipitated with anti-HA agarose and analyzed by Western blotting. (B) An in vitro ubiquitination assay was performed by incubation of purified GST-PINK1 with Flag-tagged SARM1, Myc-tagged TRAF2, or Myc-tagged TRAF6 in the presence of E1, E2 (UbcH13/Uev1a), and ubiquitin. Ubiquitination of PINK1 was detected by pull down with glutathione-agarose beads, followed by Western blot analysis for ubiquitin. (C) SARM1 promotes TRAF6-mediated PINK1 ubiquitination in SH-SY5Y cells. SH-SY5Y cells were transfected with designated constructs. Levels of PINK1 ubiquitination were determined by immunoprecipitation with anti-HA agarose, followed by Western blot analysis. (D) Ubiquitination levels are reduced in PINK1 mutants.
