A modified G-protein-coupled receptor (GPCR), having modified ligand affinity is provided by binding a G-protein-coupled receptor to a polypeptide consisting of an amino acid sequence of SEQ ID NO: 1. Furthermore, agonists for or antagonists against the modified GPCR are screened using a transformant in which the modified GPCR has been expressed. This makes it possible to provide a technique for analyzing the function of many putative GPCRs whose entities have not been clarified.
通过将 G 蛋白偶联受体与由 SEQ ID NO: 1 的氨基酸序列组成的多肽结合,提供了一种具有改良配体亲和力的改良 G 蛋白偶联受体(GPCR)。此外,还可使用表达了经修饰 GPCR 的转化体来筛选经修饰 GPCR 的激动剂或拮抗剂。这样就有可能提供一种技术,用于分析许多实体尚未明确的假定 GPCR 的功能。
