Figure 2. Structure of SVT and AP-1 and binding of SVT to c-Fos of AP-1.

Structure of SVT of Vipera lebetina turanica. A. Structure of Cobrotoxin. B. Whole cell lysates of A549 were incubated with SVT-conjugated Sepharose 4B. After precipitation, the levels of bound c-Fos were monitored by Western blot analysis. C. Docking model of SVT with c-Fos. Molecular surface representation docking model of SVT with c-Fos. doi:10.1371/journal.pone.0091508.g001
