    • Disclosed are constitutively activated, non-endogenous versions of endogenous human GPCRs comprising the following amino acid sequence region (C-terminus to N-terminus orientation) and/or the following nucleic acid sequence region (3′ to 5′ orientation) transversing the transmembrane-6 (TM6) and intracellular loop-3 (IC3) regions of the GPCR: P1AA15X  (a) and/or Pcodon(AA-codon)15Xcodon,  (b) respectively. In a 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 amino acid residues and 15 codons encoding endogenous amino acid residues, respectively; and X and Xcodon are non-endogenous lysine and non-endogenous nucleic acid region encoding lysine, respectively, located within IC3 of the non-endogenous GPCR. The purified and isolated non-endogenous human GPCRs having these mutations, and the receptors incorporated into mammalian cells, are well within the present disclosure.
    • 公开了包含以下氨基酸序列区(C末端至N末端取向)和/或跨越跨膜的以下核酸序列区(3'至5'取向)的内源性人GPCR的组成型激活非内源型 -6(TM6)和细胞内环3(IC3)区域:和/或分别。 在优选的实施方案中,P1和Pcodon是分别位于非内源性GPCR TM6内的内源性脯氨酸和编码脯氨酸的内源核酸编码区; AA15和(AA-密码子)15分别是15个内源氨基酸残基和15个编码内源氨基酸残基的密码子; X和Xcodon是分别位于非内源性GPCR的IC3内的非内源赖氨酸和编码赖氨酸的非内源核酸区域。 具有这些突变的纯化和分离的非内源性人GPCR以及并入哺乳动物细胞中的受体完全在本公开内。
