(57) [Problem] To provide a novel seven-transmembrane receptor protein, cDNA encoding the protein, an expression system of the protein, and an antibody of the protein. SOLUTION: A seven-transmembrane receptor JEG18 cDNA fragment was obtained from a leukocyte cell line Jurkat. The full length of the cDNA coding region was obtained, an expression system for a novel protein encoded by the cDNA was prepared, and the protein was expressed. Further, the antibody was prepared. 7 times transmembrane receptor protein J EG18 can be used to search for drugs that control the function of leukocytes. |
