Cat member of the cat family, the felids, which are a rapidly evolving family of mammals that share a common ancestor only 10–15 million years ago and include lions, tigers, cougars and many others. Within this family, domestic cats ("Felis catus") are part of the genus "Felis", which is a group of small cats containing about seven species (depending upon classification scheme). Members of the genus are found worldwide and include the jungle cat ("Felis chaus") of southeast Asia, European wildcat ("F. silvestris silvestris"), African wildcat ("F. s. lybica"), the Chinese mountain cat ("F. bieti"), and the Arabian sand cat ("F.
Olfactory receptor family 2 subfamily ag member 2 the largest in the genome. The nomenclature assigned to the olfactory receptor genes and proteins for this organism is independent of other organisms. [provided by RefSeq, Jul 2008]. Olfactory receptor family 2 subfamily ag member 2 Olfactory receptor family 2 subfamily AG member 2 is a protein that in humans is encoded by the OR2AG2 gene. Olfactory receptors interact with odorant molecules in the nose, to initiate a neuronal response that triggers the perception of a smell. The olfactory receptor proteins are members of a large family of G-protein-coupled receptors (GPCR) arising from single coding-exon genes. Olfactory receptors share a
