The present invention intends to provide a method for analyzing gene expression,na novel use for a receptor protein and the like. Specifically, the present inventionnprovides a method for analyzing gene expression, which is characterized by identifyingngenes, which are characteristically promoted or suppressed in certain cells or tissues bynquantitatively analyzing the individual expressed amounts of a plural number of genesncollectively, an assay kit employed in the method and the like. The present invention alsonprovides a method of screening compounds or salts thereof which alter the bindingnproperties of a novel G protein coupled receptor protein comprising an amino acidnsequence identical or substantially identical to the amino acid sequence represented bynSEQ ID NO: 9 or a salt thereof with a ligand, characterized by the use of the protein ornsalt thereof and a protein (such as a lectin) showing an affinity for a sugar chain which isnone of the ligands. |
