NOVEL PHYSIOLOGICALLY ACTIVE PEPTIDES AND UTILIZATION THEREOF

摘要

Peptides having an amino acid sequence represented by SEQ ID NO:35 or an amino acid sequence substantially identical therewith and being capable of binding to receptor proteins having an amino acid sequence represented by SEQ ID NO:1, SEQ ID NO:2 or SEQ ID NO:3 or an amino acid sequence substantially identical therewith, precursors thereof or amides, esters or salts of the same. DNAs, etc. encoding the above peptides are usable in: 1) developing receptor-binding assay systems with the use of recombinant receptor protein expression systems and screening of candidates for drugs; 2) developing drugs such as memory function improving agents, appetite improving agents or function regulating agents for uterus, kidney, prostate gland, testis or skeletal muscle; etc.
