Isolation of mouse vomeronasal receptor genes and their co-localization with specific G-protein messenger RNAs.
Four mouse vomeronasal receptors (mV1Rs) have been isolated by similarity to rat vomeronasal receptor (V1R) motifs. The four mV1Rs identified in this study are members of two distinct subfamilies. Specific in situ hybridization probes (ISH) derived from the 3' non-coding regions of the mV1R genes, were used to detect expression of a single receptor and probes from the homologous coding regions were used to detect expression of subfamily members. The ISH results showed that the mV1Rs expressing neurons were scattered in the middle/upper layer of the vomeronasal organ (VNO) sensory epithelium in serial VNO sections but were excluded from the deeper layers of the VNO sensory epithelium and these neurons were found to co-express the mRNA for the G-protein Galphai2, and were distinct from the deeper layers of the VNO sensory epithelium where the mRNA for Galphao positive neurons was located.
