SCENTS AND SENSIBILITY: A MOLECULAR LOGIC OF OLFACTORY PERCEPTION
... The completed sequence of both the murine and human genome ultimately identified 1300 odorant receptors in the mouse (12,13) and 500 in humans (14,15,16). If mice possess 20,000 genes, then as much as 5% of the genome, one in 20 genes encodes the odorant receptors. A large family of odorant receptor ...
