Abstract:
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.
Constituitively Open Voltage-Gated Kand Methods For Discovering Modulators Thereof
The present invention provides voltage-gated K channels with amino acid substitutions that produce a constitutively open phenotype when expressed in the cell. The invention includes mutated purified proteins with constitutively open voltage-gated K channel activity, for example those derived from Shaker, Shab, Shal, and Shaw family of voltage-gated K channels. The invention also includes nucleic acid encoding constitutively open voltage-gated K channels, as well as cells and transgenic animals expressing constitutively open voltage-gated K channels. Methods are provided for screening substances for ability to modulate voltage-gated K channels, by exploiting the ability of constitutively active voltage-gated K channels to affect growth or other phenotypic or genotypic characteristics in eukaryotic cells.
