Direct binding of the Duox A-loop to the DuoxA N terminus. Purified GST-tagged DuoxA N terminus was mixed with synthesized biotin-labeled Duox A-loop in binding buffer. IP, immunoprecipitation. Then, streptavidin-coupled magnetic beads were added 2 h later. The material absorbed to the beads was eluted in Laemmli sample buffer. The eluents were subjected to SDS-PAGE followed by immunoblotting (WB) using a polyclonal antibody against GST. The strongest interaction was observed between Duox1(Aloop) and DuoxA1(N) relative to Duox2(Aloop) + DuoxA2(N), Duox1(Aloop) + DuoxA2(N), and Duox2(Aloop) + DuoxA1(N) (n ≥ 3).
