1 Collectively, our data indicated that Gs-coupled receptors can activate H-Ras and subsequently the mitogen-activated protein kinases ERK1/2 by a Ca2+ -activated Ras-GEF, possibly RasGRP1, mediated by cAMP-activated Epac proteins, which then lead via Rap2B and PLC-epsilon stimulation to [Ca2+]i increase.
