The present invention relates to nucleic and amino acid sequences encoding vanilloid receptors which are vanilloid-insensitive. The present invention provides mutant vanilloid receptors which are insensitive to vanilloid, but which are capable of responding to low pH, heat and other receptor modulators. The invention particularly provides mutant vanilloid insensitive human VR1 receptors. The invention also relates to methods and assays for screening for vanilloid receptor modulators that act independent of the vanilloid binding site and modulate receptor signals independent of a functional vanilloid, or capsaicin, response. The invention further provides methods of modulating the vanilloid receptor, independent of vanilloid response.
本发明涉及编码对香草素不敏感的香草素受体的核酸和
氨基酸序列。本发明提供了对香草素不敏感但能对低 pH 值、热和其他受体调节剂产生反应的突变型香草素受体。本发明特别提供了对香草素不敏感的突变体人 VR1 受体。本发明还涉及筛选类香草素受体调节剂的方法和检测方法,这些调节剂的作用与类香草素结合位点无关,并且调节受体信号与功能性类香草素或
辣椒素反应无关。本发明进一步提供了独立于香草素反应的香草素受体调节剂的方法。
