Small GTPase Rif binds mDia2 through domains G-DID. (A) Coomassie staining of MBP or MBP-tagged mDia2 proteins (Nt and NtΔBD) that were used in a GTPase-binding assay with GST-Rif Q75L or GST as control. The presence of BD does not increase binding to active Rif in vitro. (B) An immunoblot of MBP-mDia2 proteins Nt, NtΔBD, BD-G-DID, and BD-G that were used in a GTPase binding assay with GST-Rif Q75L or GST control. Constructs Nt, NtΔBD, and BD-G-DID bound Rif, whereas construct BD-G could not be detected unless high exposure times were used. Quantification of band intensities relative to respective controls shows a 2.4-fold (A) and 3.8-fold (B) increase for MBP-Nt and a 6.0-fold (A) and 9.2-fold (B) increase for MBP-NtΔBD. There is no difference in the MBP band intensity between GST and GST-Rif (A). Panels A and B represent separate experiments.
