Another Tahitian Beauty   Leffingwell & Associates - February 14, 2002, Canton, GA announced the public release of theoretical 3-D Models of selected Human Olfactory receptors and a rapid and simple methodology for determining the putative odorant binding cavity. Olfactory receptor gene superfamily of the mouse - January 2002 - Stuart Firestein with Xinmin Zhang at Columbia University have identified the mouse OR genes from the nearly complete Celera mouse genome by a comprehensive data mining strategy. They found 1,296 mouse OR genes (including 20% pseudogenes). Human ORs cover a similar 'receptor space' as the mouse ORs, suggesting that the human olfactory system has retained the ability to recognize a broad spectrum of chemicals even though humans have lost nearly two-thirds of the OR genes as compared to mice.
