The present invention provides uses of a polypeptide having a ligand activity to a sensory epithelium neuropeptide-like receptor (SENR) which is a G protein-coupled receptor protein, and a DNA encoding the same. More specifically, the present invention provides an anti-attention-deficit-disorder or anti-narcolepsy agent, which comprises a polypeptide having a ligand activity for SENR or a salt thereof, as well as a method for screening compounds having an anti-attention-deficit-disorder or anti-narcolepsy activity or compounds having an anti-anxiety, anti-depression, anti-insomnia, anti-schizophrenia or anti-fear activity or salts thereof, which comprises using the above polypeptide or a precursor protein of the polypeptide or a salt thereof.
本发明提供了一种对属于 G 蛋白偶联受体蛋白的感觉上皮神经肽样受体(SENR)具有配体活性的多肽及其编码 DNA 的用途。更具体地说,本发明提供了一种抗注意力缺陷障碍或抗嗜睡症的药物,它包括对 SENR 具有配体活性的多肽或其盐,以及一种筛选具有抗注意力缺陷障碍或抗嗜睡症活性的化合物或具有抗焦虑、抗抑郁、抗失眠、抗过敏、抗过敏和抗过敏活性的化合物的方法、抗抑郁、抗失眠、抗精神分裂症或抗恐惧活性的化合物或其盐,其中包括使用上述多肽或该多肽的前体蛋白或其盐。
