Figure 5. Sumoylation impairs interaction of DRIL1 with E2F1 in vitro.

Figure 5

(A) Coomassie staining of the gel showing expression of recombinant GST-fusion proteins purified from bacteria, asterix for full length recombinant GST-E2F1 and GST. (B) GST pull-down assay of in vitro translated unsumoylated (DRIL1) or sumoylated (DRIL1-S) DRIL1, and Luciferase control, with GST-E2F1 and GST control. (C) Quantification by ImageJ software of DRIL1 species recovered by pulldown vs input (% of input band intensity).
