    • A single chain, polypeptide fusion protein, comprising: a non-cytotoxic protease, which cleaves a protein of the exocytic fusion apparatus of a nociceptive sensory afferent; a galanin Targeting Moiety that binds a Binding Site on the nociceptive sensory afferent, which can undergo endocytosis to be incorporated into an endosome; a protease cleavage site where the fusion protein is cleavable by a protease located between the non-cytotoxic protease and the galanin Targeting Moiety; a translocation domain that translocates the protease from within an endosome, across the endosomal membrane and into the cytosol of the nociceptive sensory afferent; a first spacer from 4 to 25 amino acids between the non-cytotoxic protease and protease cleavage site; and a second spacer comprising from 4 to 35 residues between the galanin Targeting Moiety and translocation domain. Nucleic acid sequences encoding the polypeptide fusion proteins, methods of preparing same and uses thereof are also described.

    • The present invention is directed to non-cytotoxic protein conjugates for inhibition or reduction of exocytic fusion in a nociceptive sensory afferent cell. The protein conjugates comprise: (i) a galanin Targeting Moiety (TM), wherein the TM is an agonist of a receptor present on a nociceptive sensory afferent cell, and wherein the receptor undergoes endocytosis to be incorporated into an endosome within the nociceptive sensory afferent cell; (ii) a non-cytotoxic protease or a fragment thereof, wherein the protease or protease fragment is capable of cleaving a protein of the exocytic fusion apparatus of the nociceptive sensory afferent cell; and (iii) a Translocation Domain, wherein the Translocation Domain translocates the protease or protease fragment from within the endosome, across the endosomal membrane, and into the cytosol of the nociceptive sensory afferent cell. Nucleic acid sequences encoding the protein conjugates, methods of preparing same and uses thereof are is also described.
    • 本发明涉及用于抑制或减少伤害性感觉传入细胞中的胞外融合的非细胞毒性蛋白质缀合物。 所述蛋白质缀合物包括:(i)甘丙肽靶向部分(TM),其中所述TM是存在于伤害性感觉传入细胞上的受体的激动剂,并且其中所述受体经受内吞作用以掺入伤害性感觉传入物内的内体 细胞; (ii)非细胞毒性蛋白酶或其片段,其中所述蛋白酶或蛋白酶片段能够切割伤害性感觉传入细胞的胞外融合装置的蛋白质; 易位结构域(Translocation Domain),其中易位域将位于内体内的蛋白酶或蛋白酶片段穿过内体膜并转移到伤害性感觉传入细胞的胞质溶胶中。 还描述了编码蛋白质缀合物的核酸序列,其制备方法及其用途。
