    • The present invention relates to a novel glial cell line-derived neurotrophic factor receptor beta (GDNFR-β) and novel glial cell line-derived neurotrophic factor receptor gamma 1 and 2 (GDNFR-ηl and GDNFR-η2). The receptors of the present invention share high homology with glial cell line-derived neurotrophic factor receptor alpha and have been named GDNFR-β, GDNFR-η1 and GDNFR-η2. More specifically, isolated nucleic acid molecules are provided encoding human GDNFR-β, GDNFR-η1 and GDNFR-η2 receptors. GDNFR-β, GDNFR-η1 and GDNFR-η2 polypeptides are also provided, as are vectors, host cells and recombinant methods for producing the same. The invention further relates to screening methods for identifying agonists and antagonists of GDNFR-β, GDNFR-η1 and GDNFR-η2 activity. Also provided are diagnostic and therapeutic methods for disorders and diseases including Parkinson's disease, thyroid tumor, kidney failure and gut dysfunction.
    • 本发明涉及新型神经胶质细胞系衍生的神经营养因子受体β(GDNFR-β)和新型神经胶质细胞系衍生的神经营养因子受体γ1和2(GDNFR-γ1和GDNFR-γ2)。 本发明的受体与神经胶质细胞系衍生的神经营养因子受体α具有高同源性,并且被命名为GDNFR-β,GDNFR-γ1和GDNFR-γ2。更具体地,提供分离的核酸分子,其编码人GDNFR- β,GDNFR-γ1和GDNFR-γ2受体。 还提供了GDNFR-β,GDNFR-γ1和GDNFR-γ2多肽,载体,宿主细胞和用于产生它们的重组方法也是如此。 本发明还涉及用于鉴定GDNFR-β,GDNFR-γ1和GDNFR-γ2活性的激动剂和拮抗剂的筛选方法。 还提供了用于疾病和疾病的诊断和治疗方法,包括帕金森病,甲状腺肿瘤,肾衰竭和肠功能障碍。
