The present invention relates to the discovery of several genes of the domestic cat (Felis catus) associated with taste perception. The invention provides, inter alia, the nucleotide sequence of the feline Tas1r1, Tas1r2, and Tas1r3 receptor genes, the amino acid sequences of the polypeptides encoded thereby, and antibodies to the polypeptides. The present invention also relates to methods for screening for compounds that modify the genes' function or activity, the compounds identified by such screens, and mimetics of the identified compounds. The invention further provides methods for modifying the taste preferences, ingestive responses, or general behavior of a mammal, such as a cat, by administering compounds that affect the function or activity of the gene or the polypeptide encoded thereby.
An isolated and purified T1R receptor polypeptide comprising:
A feline T1R receptor produced according to a method comprising the steps of:
An isolated and purified T1R receptor comprising at least one extracellular domain of a feline T1R receptor polypeptide, said extracellular domain comprising amino acids 1-571 of SEQ ID NO:2, amino acids 628-641 of SEQ ID NO:2, amino acids 705-731 of SEQ ID NO:2, or amino acids 787-794 of SEQ ID NO:2.
An isolated and purified T1R receptor comprising at least one transmembrane domain of a feline T1R receptor polypeptide, said transmembrane domain comprising amino acids 572-594 of SEQ ID NO:2, amino acids 610-627 of SEQ ID NO:2, amino acids 642-664 of SEQ ID NO:2, amino acids 681-704 of SEQ ID NO:2, amino acids 731-754 of SEQ ID NO:2, amino acids 767-786 of SEQ ID NO:2, or amino acids 795-812 of SEQ ID NO:2.
An isolated and purified T1R receptor comprising an intracellular domain of a feline T1R receptor, said intracellular domain comprising amino acids 595-609 of SEQ ID NO:2, amino acids 665-680 of SEQ ID NO:2, amino acids 755-766 of SEQ ID NO:2, or amino acids 813-865 of SEQ ID NO:2.
