Abstract

There are ∼1000 olfactory receptor genes in mammals, forming the largest multigene family. Identification of the entire repertoires of olfactory receptor genes from various species and extensive phylogenetic analyses revealed dynamic change of this gene family in evolution.

Keywords:

  • olfactory receptor;
  • chemosensory receptor;
  • phylogenetic analysis;
  • multigene family;
  • birth-and-death evolution
