  • Publication number: 20230266316
    Abstract: An object of the present invention is to demonstrate the existence of a heterodimer of somatostatin receptor subtype 1 (SSTR1) and somatostatin receptor subtype 4 (SSTR4) and also to provide a method for screening a factor that binds to such a heterodimer and the heterodimer that can be used in the screening method. A transformant expressing a heterodimer of somatostatin receptor subtype 1 and somatostatin receptor subtype 4, into which DNA encoding somatostatin receptor subtype 1 and DNA encoding somatostatin receptor subtype 4 have been introduced. A method for screening a compound that interacts with a heterodimer of somatostatin receptor subtype 1 and somatostatin receptor subtype 4, comprising selecting the compound that interacts with the heterodimer from test compounds.

  • Publication number: 20090298775
    Abstract: The present invention provides a method of measuring the activity of neprilysin, etc. More specifically, the present invention provides a method of measuring the activity of neprilysin in nerve cells; a method of screening a protein, a peptide or a compound enhancing the activity or expression of neprilysin in nerve cells by measuring the activity of neprilysin; a method of enhancing the activity or expression of neprilysin; and so on. Thus, the compound enhancing the activity and/or expression of neprilysin, which is obtained by the screening method characterized by using the method of measuring the activity of neprilysin in accordance with the present invention, is useful as a preventive and/or therapeutic agent for Alzheimer's disease. The method of measuring the activity of the present invention can be used for presymptomatic diagnosis of Alzheimer's disease.
