The present invention relates to polypeptides capable of modulating odorant receptor activation. In particular, the present invention provides polypeptides (e.g., type 3 muscarinic actetylcholine receptor M3) capable of enhancing odorant receptor activation. The present invention further provides assays for the detection of ligands specific for various odorant receptors. Additionally, the present invention provides methods of screening for polypeptide polymorphisms and mutations associated with odorant receptor activation (e.g., polymorphisms and mutations associated with muscarinic actetylcholine receptor polypeptides (e.g., M1, M2, M3, M4, M5)), as well as methods of screening for therapeutic agents, ligands, and modulators of such proteins.
本发明涉及能够调节气味受体活化的
多肽。特别是,本发明提供了能够增强气味受体活化的
多肽(如 3 型毒蕈碱动
乙酰胆碱受体 M3)。本发明进一步提供了检测各种气味受体特异性
配体的检测方法。此外,本发明还提供了筛选与气味受体激活相关的
多肽多态性和突变的方法(例如,与毒蕈碱动
乙酰胆碱受体
多肽(例如,M1、M2、M3、
M4、M5)相关的多态性和突变),以及筛选此类蛋白质的治疗剂、
配体和调节剂的方法。
