|abstract=By searching the human and mouse genomic databases we found two G-protein-coupled receptors, [[GPR139]] and [[GPR142]], with characteristic motifs of the rhodopsin family of receptors. The gene for [[GPR139]] maps to chromosome 7F1 of mouse and 16p12.3 of human and that for [[GPR142]] to 11E2 of mouse and 17q25.1 of human. We isolated [[GPR139]] from a cDNA library of adult mouse brain and [[GPR142]] from a cDNA library of brains from 15-day-old mouse embryos. [[GPR139]] mRNA was predominantly expressed in specific areas of human and mouse brains, whereas [[GPR142]] mRNA showed a more ubiquitous expression both in the brain and in various peripheral glands and organs. A 50% identity and a 67% homology at the amino-acid level between the two receptors and only 20-25% identity with other G-protein-coupled receptors established them as a new subbranch within the phylogenetic tree and hints at a common or similar ligand(s). Preliminary results suggest that the cognate ligand is present in brain extracts and is, most likely, a small peptide. [[GPR139]] signal transduction in Chinese hamster ovary cells requires coupling to an inhibitory G-protein and is mediated by phospholipase C. Dimer formation may be necessary for proper function.
