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.
本发明提供了一种具有配体活性的多肽对感觉上皮神经肽样受体(SENR)的用途,该受体是一种G蛋白偶联受体蛋白,以及编码该多肽的DNA。更具体地,本发明提供了一种抗注意缺陷失调或抗嗜睡症药剂,它包括具有SENR配体活性或其盐的多肽,以及一种筛选具有抗注意缺陷失调或抗嗜睡症活性或具有抗焦虑、抗抑郁、抗失眠、抗精神分裂症或抗恐惧活性或其盐的化合物的方法,该方法包括使用上述多肽或其前体蛋白或其盐。
