Mechanisms for Reversible Regulation between G13 and Rho Exchange Factors [PDF]
Journal of Biological Chemistry, 2002 The heterotrimeric G proteins, G(12) and G(13), mediate signaling between G protein-coupled receptors and the monomeric GTPase, RhoA. One pathway for this modulation is direct stimulation by Galpha(13) of p115 RhoGEF, an exchange factor for RhoA. The GTPase activity of both Galpha(12) and Galpha(13) is increased by the N terminus of p115 Rho guanine ...

Immunodetection with the antisera indicated that the 43-kDa protein is expressed ubiquitously at low levels (0.005-0.05% of membrane protein) in tissues ...
