    • The present invention provides isolated DNA molecules comprising a DNA segment encoding a glucagon receptor. Also provided are DNA constructs comprising a first DNA segment encoding a glucagon receptor operably linked to additional DNA segments required for the expression of the first DNA segment, as well as host cells containing such DNA constructs. The present invention also provides amethod for detecting the presence of glucagon antagonists, comprising the steps of (a) exposing a compound in the presence of a glucagon agonist to a recombinant glucagon receptor coupled to a response pathway under conditions and for time sufficient to allow binding of the compound to the receptor and an associated response through the pathway, and (b) detecting a reduction in the stimulation of the response pathway resulting from the binding of the compound to the glucagon receptor, relative to the stimulation of the response pathway by the glucagon agonist alone and therefrom determining the presence of a glucagon antagonist.
    • 本发明提供了分离的DNA分子,其包含编码胰高血糖素受体的DNA区段。 还提供了DNA构建体,其包含编码与第一DNA片段表达所需的另外DNA片段可操作地连接的胰高血糖素受体的第一DNA片段,以及含有该DNA构建体的宿主细胞。 本发明还提供了检测胰高血糖素拮抗剂的存在的方法,其包括以下步骤:(a)在有足够的条件和足以允许结合的时间内将化合物在胰高血糖素激动剂存在下暴露于与响应途径偶联的重组胰高血糖素受体 化合物与受体的相关反应和通过该途径的相关应答,以及(b)检测由化合物与胰高血糖素受体的结合产生的反应途径的刺激相对于由 胰高血糖素激动剂单独和由此决定胰高血糖素拮抗剂的存在。
