| NPY2R | 93.7 | 93.7 | 92.9 |
| NPY4R | 85.9 | 77.1 | 75.7 |
| NPY5R | 85.4 | 81.2 | 87.6 |
| NPY5R * | 93.5 | 89.0 | 91.9 |

[i] Amino acid identities are given for aligned NPY receptors over full coding regions, in the pig, human (accession nos. M88461, NM_000910,Z66526, NM_006174, NM_006173), and mouse (accession nos. Z18280, D86238,U40189, AF049329, U58367). NPY5R* represents the NPY5Rsequences without the third intracellular loop in the alignment.
