Interaction of MINERVA with Keap1 through its C-terminal region. (a) HEK293 cells were co-transfected with HA-tagged Keap1 and either one of the FLAG-tagged MINERVAFL, MINERVAΔN, or MINERVAΔC. HA-Keap1 was immunoprecipitated with anti-HA with protein A-Sepharose and the immunoprecipitates were examined by western blots using respective antibodies. Actin was used as a loading control. Full blot can be found in Figure S7. (b) Surface plasmone resonance (SPR) analysis of MINERVAFL and Keap1 showing micromolar binding affinity between two proteins. The average and standard deviations of ka, kd, and KD are calculated from values obtained from two separate experiments.
