This family includes a number of gustatory and odorant receptors mainly from insect species such as Anopheles gambiae (African malaria mosquito) and Drosophila melanogaster (Fruit fly). They are classified as G-protein-coupled receptors (GPCRs), or seven-transmembrane receptors. They show high sequence divergence, consistent with an ancient origin for the family.
