Presence of Tas2r genes in seven species in the order Carnivora.

Note: Only Tas2rs with a predicted intact open reading frame in at least one species in Carnivora are listed. +, intact gene present; ps, predicted gene is pseudogenized due to either open reading frame-shifting mutations or premature stop codons;—, Tas2r ortholog is not found in the genome database from that species. Numbers in parentheses are those used in Li and Zhang [6];*, nomenclature of predicted Tas2r in NCBI. The seal Tas2r38 (+?) has a longer N-terminal and a predicted octahelical transmembrane domain, so it is uncertain of whether it is intact. For walrus, Tas2r40 (+?) lacks the prototypic seven-transmembrane helices for G-protein-coupled receptors and is thus unlikely to be functional [23].Presence of Tas2r genes in seven species in the order Carnivora.
