Chemical cross-link analysis of hMSH2, hMSH3, and hMSH6 protein complexes. The in vitro transcribed and translated proteins were mixed, cross-linked, and processed for immunoprecipitation (see Materials and Methods). (A) Lanes 1–4, immunoprecipitates of individually cross-linked hMSH2 (lane 1), hMSH3 (lane 2), hMSH6 (lane 3), and luciferase (lane 4); lanes 5–10, immunoprecipitates of the cross-linked complexes hMSH2 and hMSH3 (lane 5), hMSH2 and hMSH6 (lane 6), hMSH2 and luciferase (lane 7), hMSH2 (unlabeled) and hMSH3 (lane 8), hMSH2 (unlabeled) and hMSH6 (lane 9), hMSH2 (unlabeled) and luciferase (lane 10). (B) Lanes 11–18, cross-linked complexes before immunoprecipitation including hMSH2 (lane 11), hMSH3 (lane 12), hMSH6 (lane 13), luciferase (lane 14), hMSH2 and hMSH3 (lane 15), hMSH2 and hMSH6 (lane 16), hMSH3 and hMSH6 (lane 17), hMSH2 and luciferase (lane 18), hMSH3 and luciferase (lane 19), hMSH6 and luciferase (lane 20).
