    • To facilitate the study of Nogo-66 interaction with its neuronal receptors, and to explore therapeutic opportunities, the present invention provides mutant human Nogo-66 domain-based proteins that do not aggregate during isolation or purification procedures, and methods for using these proteins. Aggregates of Nogo-66 domain containing proteins do not effectively or efficiently bind to the NgR1 receptor, and therefore limit the utility of Nogo-66 domain-based reagents. To overcome aggregation problems, the invention provides proteins that comprise a mutant human Nogo-66 domain, wherein the cysteine at position 47 of the wild-type human Nogo-66 domain is mutated. The invention also provides for various Nogo-66 domain fusion reporter proteins that are able to bind to NgR1, and therefore can be used in high-throughput assays to identify drug candidate compounds that can block binding of the Nogo-66 domain to NgR1, indicating that these compounds may be potential therapeutic agents for neurodegenerative diseases and neuronal repair.
    • 为了促进Nogo-66与其神经元受体的相互作用的研究,并且为了探索治疗机会,本发明提供了在分离或纯化过程中不聚合的突变型人Nogo-66结构域的蛋白质,以及使用这些蛋白质的方法。 含有Nogo-66结构域的蛋白质的聚集体不能有效或有效地结合NgR1受体,因此限制了Nogo-66结构域的试剂的效用。 为了克服聚集问题,本发明提供了包含突变人Nogo-66结构域的蛋白质,其中野生型人Nogo-66结构域的位置47处的半胱氨酸被突变。 本发明还提供了能够结合NgR1的各种Nogo-66结构域融合报道蛋白,因此可用于高通量测定以鉴定可阻断Nogo-66结构域与NgR1结合的药物候选化合物,表明 这些化合物可能是神经变性疾病和神经元修复的潜在治疗剂。
