The genomic DNA encoding bovine Thyrotropin-Releasing Hormone Receptor (TRHR) was isolated from a bovine (Holstein) genomic library. Using PCR fragments of bovine candidate TRHR Transmembrane domain (TMD-III-IV) and C-terminus domain of mouse TRHR cDNA as probes, 9 × 105 plaques were screened to obtain several clones each containing the N-terminus or C-terminus domain. The bovine TRHR gene encoded 398 amino acids and has a long intron. The identity of the deduced amino acid sequence of bovine TRHR exceeded 88% that of mouse, rat or human. RT-PCR analysis indicated TRHR mRNA to be expressed in the pituitary and brain.
