(57) [Summary] (with correction) [Problem] To provide a novel bioactive peptide and its use. SOLUTION: It contains an amino acid sequence identical or substantially identical to a specific amino acid sequence derived from mouse, and contains an amino acid sequence identical or substantially identical to any one of three specific amino acid sequences derived from rat. The present invention relates to a peptide having the ability to bind to a galanin receptor protein, a precursor thereof, an amide thereof, an ester thereof, or a salt thereof. D encoding the peptide of the present invention NA and the like include (i) development of a receptor binding assay system using a recombinant receptor protein expression system and screening of drug candidate compounds, and (ii) memory function improving agents, appetite improving agents or uterus and kidney having few side effects. , Prostate, testis or skeletal muscle. |
