| Outline of Final Research Achievements |
Ghrelin is a 28-amino acid orexigenic peptide hormone mainly produced by the stomach. The acylation of the third amino residue at ghrelin is required for its binding and activation of the ghrelin receptor. At first des-acyl ghrelin (DAG) was considered an inactive form of ghrelin, but now the DAG is believed to be a biologically active. To clone the DAG receptor(s), we performed a biotinyl DAG binding assay using the mouse adult brain cDNA expression library transfected cells. We succeeded in the identification of a DAG receptor candidate gene. This candidate gene product bound to the biotinyl DAG in vitro. Future study is required to determine the precise mechanism(s) of DAG action.
