    • An endogenous receptor to human prokineticins 1 and 2, which acts not on the digestive organ contraction or spermatogenesis functions but on the central functions, in particular, the nerve cell death−inhibitory function, is identified. A method of screening a substance capable of controlling the central functions, for example, a substance useful as a remedy for dementia, cerebral accident and/or hyperalgesia, which are known as being associated with nerve cell death, with the use of the above−described receptor and/or cells having been transformed by the receptor. To obtaining nerve cell death inhibitors and/or remedies for hyperalgesia, nerve cell death inhibitor screening tools comprising the prokineticin receptor GPRg2, a functionally equivalent variant thereof or a polypeptide homologous therewith, and nerve cell death inhibitor screening tools comprising transformant cells which have been transformed by an expression vector containing polynucleotide encoding one of the above−described polypeptides and express the polypeptide. A process for producing a medicinal composition for inhibiting the nerve cell death and/or treating hyperalgesia containing, as the active ingredient, a substance capable of modifying the activity of the above−described receptor which can be obtained by using any of the above−described screening tools or the screening method.
    • 鉴定出不是对消化器官收缩或精子发生功能起作用但对中枢功能,特别是神经细胞死亡抑制功能的人促肌球蛋白素1和2的内源性受体。 使用上述方法筛选能够控制中枢功能的物质的方法,例如可用作痴呆,脑部事故和/或痛觉过敏的物质的物质,其被称为与神经细胞死亡有关, 已经被受体转化的受体和/或细胞。 为了获得神经细胞死亡抑制剂和/或用于痛觉过敏的补救措施,神经细胞死亡抑制剂筛选工具包括原动力蛋白受体GPRg2,其功能等同变体或与其同源的多肽,以及神经细胞死亡抑制剂筛选工具,其包含转化细胞 通过含有编码上述多肽之一的多核苷酸的表达载体,并表达多肽。 一种抑制神经细胞死亡和/或治疗痛觉过敏的药物组合物的制造方法,其含有能够改变上述受体活性的物质作为活性成分,该物质可以通过使用上述 筛选工具或筛选方法。
