The ligand-binding domain of human retinoic acid receptor alpha (hRAR alpha) was photoaffinity-labeled with a fluorescent retinoid, ADAM-3, by the use of a recombinant fused protein constructed from a maltose-binding protein and the E/F-domain of hRAR alpha (MBP-RAR alpha/E), which was expressed in E. coli. The labeled site was identified as Arg-589 (this corresponds to amino acid residue 385 of hRAR alpha) or a residue in its vicinity.
通过使用由麦芽糖结合蛋白和人视黄酸受体α(hRARα)的E/F结构域构建的重组融合蛋白(MBP-RARα/E),该融合蛋白在大肠杆菌中表达,人视黄酸受体α(hRARα)的配体结合结构域用荧光类视黄醇ADAM-3进行了光亲和标记。标记位点被确定为Arg-589(这对应于hRARα的氨基酸残基385)或其附近的一个残基。
