To find out the binding partners of EhRacM, crosslinking and coimmunoprecipitation were performed. Then, eluted samples were submitted to Mass Spectrometry and Proteomics Core Facility, Johns Hopkins University School of Medicine and analyzed by mass spctrometry (shotgun proteomics). The coimmunoprecipitation and following analysis were conducted three times.
