Figure 6. IBR-R2 but not full length parkin promotes synphilin-1ubiquitination.

Figure 6

In vitro ubiquitination reaction was carried out with synphilin-1 as a substrate in the absence of parkin (i.e. –E3) or in the presence of MBP-parkin (FL) or IBR-R2 in combination with either UbcH7, Ubc13 or no E2 (as indicated). Parkin-mediated ubiquitination of synphilin-1 was analyzed by means of anti-synphilin-1 immunoblotting (top panel) whereas parkin-mediated self ubiquitination was analyzed by means of anti-parkin immunoblotting (bottom panel).
