FIGURE 8.
Substitution of TWEAK Tyr176 disrupts Fn14-TWEAK interaction. Top, immunoblot analysis of IVTT lysates using anti-FLAG antibody showing equal expression of sTWEAK and sTWEAK Tyr176 variants. Bottom, double sandwich ELISA depicting binding of sTWEAK and TWEAK Tyr176 variants to Fn14. sTWEAK shows significantly higher binding as compared with no DNA lysate control, and TWEAK Tyr176 variants show significantly lower binding as compared with sTWEAK (**, p < 0.001).
