We show that the small GTPase RalA associates with both LPA ( 1 ) and LPA ( 2 ) in human embryonic kidney ( HEK 293 ) cells and that stimulation of LPA ( 1 ) receptors with LPA triggers the activation of RalA Hofer et al., Curr Biol 1998

Lysophosphatidic acid (LPA) and epidermal growth factor (EGF), which activate both Ras dependent and Ras independent signaling pathways [ 10,11 ], rapidly activated Ral
