Novel g protein-coupled receptor protein and dna thereof

摘要

The present invention provides a novel G protein-coupled receptor protein comprising the same or substantially the same amino acid sequence as that represented by SEQ ID NO: 1 or salts thereof, and a polynucleotide encoding the same. The present invention also provides a use such as pharmaceuticals, etc. The G protein-coupled receptor protein of the present invention, its partial peptides, or salts thereof and the polynucleotides encoding the receptor protein or its partial peptide (e.g. DNA, RNA, and its derivatives) can be used for; 1) determination of ligands (agonists); 2) preparation of antibodies and antisera; 3) construction of recombinant receptor protein expression systems; 4) development of the receptor binding assay systems using the expression systems and screening of pharmaceutical candidate compounds; 5) effecting drug design based on comparison with structurally similar ligand receptors; 6) reagents for preparation of probes and PCR primers for gene diagnosis; 7) production of transgenic animals; and 8) pharmaceutical drugs for the gene prophylaxis and gene therapy.
