粘附G蛋白偶联受体(GPCR)具有一个长的N端胞外结构域和一个七跨膜结构域。大多数粘附GPCR是孤儿受体,其激活和信号转导机制尚不清楚。GPR56和Latrophilin 1属于粘附性GPCR。我们成功制备了抗人GPR56单克隆抗体,并构建了几个突变体。使用突变体的分析表明,Latrophilin 1的胞外结构域具有抑制Latrophilin 1跨膜结构域的激活以及GPR56跨膜激活的能力。
英文摘要
Adhesion G protein-coupled receptors(GPCRs) have a long N-terminal extracellular domain and a seven-transmembrane domain. Most of adhesion GPCRs are orphan receptors, and the activation and signal transduction mechanisms remain to be clarified. GPR56 and Latrophilin1 belong to adhesion GPCRs. We succeed in preparing the monoclonal antibody against human GPR56, which inhibits the glioma cell migration, and have constructed several mutants. Analysis using mutants showed that an extracellular domain of Latrophilin1 has an ability to inhibit the activation of Latrophilin1 transmembarane domain as well as the GPR56 transmembrane activation.
