Photoaffinity labeling (PAL) is widely used for the identification of ligand-binding proteins and elucidation of ligand-binding sites. PAL has also been employed for the characterization of G protein-coupled receptors (GPCRs); however, a limited number of reports has successfully identified their cross-linked amino acids. This report is the first of its kind to determine the cross-link position of the human A adenosine receptor by PAL with the novel diazirine-based photoaffinity probe .
光亲和标记(PAL)被广泛用于鉴定配体结合蛋白和阐明配体结合位点。PAL也已用于G蛋白偶联受体(GPCR)的表征;然而,成功鉴定其交联氨基酸的报道数量有限。本报告首次通过使用新型基于重氮环丙烷的光亲和探针,利用PAL确定人A腺苷受体的交联位置。
