The olfactory (OR) and vomeronasal receptor (VR) repertoires are collectively encoded by 1700 genes and pseudogenes in the mouse genome. The are among the largest gene families in mammals. Yet most only have coding sequences annotated in existing databases, and many lack experimental support due to the similarity between them and their unusual monogenic, sensory cell-specific expression in olfactory tissues.
The aim of the olfactory transcriptomes project was to catalogue the genes expressed in the two major olfactory tissues of C57BL/6J mice, the olfactory mucosa (OM) and vomeronasal organs (VNO). Then to use these data to generate new, extended gene annotations for the OR and VR gene repertoires.
The raw sequence data are available from the European Nucleotide Archive (ENA) under accessions PRJEB2572 and PRJEB1365, and can be reused without restriction.
