N2 - Lysophosphatidic acid (LPA) has wide-ranging effects on many different cell types, acting throughG-protein-coupled receptors such as LPAR6. We show that Xenopus lpar6 is expressed from lateblastulae and is enriched in the mesoderm and dorsal ectoderm of early gastrulae. Expression ingastrulae is an early response to FGF signalling. Transcripts for lpar6 are enriched in the neuralplate of Xenopus neurulae and loss of function caused forebrain defects, with reduced expressionof telencephalic markers (foxg1, emx1 and nkx2-1).
