LPA (lysophosphatidic acid), the simplest of al glycerophospholipids, is a potent inducer of cell proliferation, migration and survival. It does so by activating its cognate G-protein-coupled receptors, four of which have been identified. LPA receptors couple to at least three distinct G-proteins and thereby activate multiple signal transduction pathways, particularly those initiated by the small GTPases Ras, Rho and Rac. Our recent work has shown that LPA signals Rac activation via the Tiam1 GDP/GTP exchange factor and thereby stimulates cell migration. Here we discuss recent progress in our understanding of LPA action.
