The invention provides isolated polypeptides that stimulate gastrointestinal smooth muscle contraction, including human prokineticin 1 and human prokineticin 2 polypeptides, and functional fragments and modifications thereof. Also provided are methods of stimulating gastrointestinal smooth muscle contraction in a mammal, by administering to the mammal an effective amount of a prokineticin polypeptide. The invention also provides nucleic acid molecules encoding a prokineticin polypeptide, and antibodies that selectively bind a prokineticin polypeptide. Further provided are methods of identifying a prokineticin receptor ligand, agonist or antagonist.
本发明提供了刺激胃肠道平滑肌收缩的分离多肽,包括人促激肽 1 和人促激肽 2 多肽及其功能片段和修饰。本发明还提供了通过向哺乳动物施用有效量的促激肽多肽来刺激哺乳动物胃肠道平滑肌收缩的方法。本发明还提供了编码促激肽多肽的核酸分子,以及选择性结合促激肽多肽的抗体。本发明还提供了鉴定促红细胞生成素受体配体、激动剂或拮抗剂的方法。
