NON-ENDOGENOUS, CONSTITUTIVELY ACTIVATED HUMAN G PROTEIN-COUPLED RECEPTORS |
摘要 |
Disclosed herein are constitutively activated, non-endogenous versions of endogenous human G protein-coupled receptors comprising (a) the following amino acid sequence region (C-terminus to N-terminus orientation) and/or (b) the following nucleic acid sequence region (3' to 5' orientation) transversi ng the transmembrane-6 (TM6) and intracellular loop-3 (IC3) regions of the GPCR : (a) P1 AA15 X and/or (b) Pcodon (AA-codon)15 Xcodon, respectively. In a most preferred embodiment, P1 and Pcodon are endogenous proline and an endogenous nucleic acid encoding region encoding proline, respectively, located within TM6 of the non-endogenous GPCR; AA15 and (AA-codon)15 are 15 endogenous amin o acid residues and 15 codons encoding endogenous amino acid residues, respectively; and X and Xcodon are non-endogenous lysine and a non-endogenou s nucleic acid encoding region encoding lysine, respectively, located within I C3 of the non-endogenous GPCR. Because it is most preferred that the non- endogenous human GPCRs which incorporate these mutations are incorporated in to mammalian cells and utilized for the screening of the candidate compounds, t he non-endogenous human GPCR incorporating the mutation need not be purified an d isolated per se (i.e., these are incorporated within the cellular membrane o f a mammalian cell), although such purified and isolated non-endogenous human GPCRs are well within the purview of this disclosure. |
