  • Publication number: 20090205061
    Abstract: 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.

  • Patent number: 7541158
    Abstract: The present invention relates to the discovery of several genes of the domestic dog (Canine familiaris) associated with taste perception. The invention provides, inter alia, the nucleotide sequence of the canine 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 dog by administering compounds that affect the function or activity of the gene or the polypeptide encoded thereby.

  • Publication number: 20070279593
    Abstract: This invention discloses a visual presenter with built-in central control system capable of remotely controlling external display device, operating image capturing device, and switching input sources. The conversion of input video format into output video format is in operation even when the visual presenter is in Stand-by mode. A universal remote is further incorporated to consolidate the operation of other external devices. An electronic whiteboard can be connected via attached PC to be displayed on external projector greatly improved the multimedia experience.
