The microevolution of V1r vomeronasal receptor genes in mice.

ABSTRACT: Vomeronasal sensitivity is important for detecting intraspecific pheromonal cues as well as environmental odorants and is involved in mating, social interaction, and other daily activities of many vertebrates. Two large families of seven-transmembrane G-protein-coupled receptors, V1rs and V2rs, bind to various ligands to initiate vomeronasal signal transduction. Although the macroevolution of V1r and V2r genes has been well characterized throughout vertebrates, especially mammals, little is known about their microevolutionary patterns, which hampers a clear understanding of the evolutionary forces behind the rapid evolutionary turnover of V1r and V2r genes and the great diversity in receptor repertoire across species. Furthermore, the role of divergent vomeronasal perception in enhancing p
