Sequence diversity and genomic organization of vomeronasal receptor genes in the mouse.

ABSTRACT: The vomeronasal system of mice is thought to be specialized in the detection of pheromones. Two multigene families have been identified that encode proteins with seven putative transmembrane domains and that are expressed selectively in subsets of neurons of the vomeronasal organ. The products of these vomeronasal receptor (Vr) genes are regarded as candidate pheromone receptors. Little is known about their genomic organization and sequence diversity, and only five sequences of mouse V1r coding regions are publicly available. Here, we have begun to characterize systematically the V1r repertoire in the mouse. We isolated 107 bacterial artificial chromosomes (BACs) containing V1r genes from a 129 mouse library. Hybridization experiments indicate that at least 107 V1r-like sequences reside on
