Figure Lengend Snippet: Figure 5. TRAF6 binds aSYN and enhances its ubiquitination with atypical chains. (A) HEK cells were transfected with FLAG–TRAF6 and MYC–aSYN wt or A53T (mut). Lysates were immunoprecipitated with anti-FLAG agarose beads and bound proteins were revealed with anti-MYC and anti-FLAG antibodies. Inputs were tested for the expression of TRAF6 and aSYN proteins. (B) Cells were transfected with HA–ubiquitin, MYC–aSYN (wt or A53T) and FLAG– TRAF6 (wt or DN). For in vivo ubiquitination assay, lysates were immunoprecipitated with anti-MYC antibody. Immunoprecipitates and lysates were analyzed with anti-MYC, anti-FLAG and anti-HA antibodies. (C) HA–ubiquitin mutants in which only the indicated lysine residue is available for chain formation were used. Wt and K0 ubiquitin were included as controls. In vivo ubiquitination of aSYN wt was performed as in (B).
Article Snippet: Mouse monoclonal (#2647) and rabbit polyclonal (#2628) anti-aSYN antibodies were from Cell Signaling.
