Receptor stimulation induces translocation of RHOA from the cytosol to the plasma membrane and subsequent activation of RHOA. Rho guanine nucleotide exchange factor 28 (p190RhoGEF, ARHGEF28) is a specific activator of RHOA that stimulates the exchange of GDP for GTP. In neuronal cells p190RhoGEF binds to and activates RHOA with its Dbl homology/pleckstrin homology domain (van Horck et al. 2001).
