Fig. 1. PLCE1 interacts with Rac1 and RhoA.
a–c Immunoprecipitation of PLCE1 with Rho GTPase, Rac1 (a), RhoA (b), and Cdc42 (c) in cultured podocytes. Immunoblotting showed that PLCE1 interacts with Rac1 and RhoA but not with Cdc42. d–e FLAG-PLCE1 expressed in HEK293 cells was precipitated by GST- Rac1 (d) and GST-RhoA (e). Ponceau red staining at the top shows the GST proteins used. f–i Costaining of PLCE1 with WT1 (f), SYNAPTOPODIN (g), Rac1 (h) and RhoA (i) using immunofluorescence in adult rat glomeruli. PLCE1 colocalized with Rac1 and RhoA in podocyte cell bodies. Immunoprecipitation (IP) and pulldown (PD) experiments are representative of more than three experiments.
