| Research Abstract |
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.
