Abstract From the Canadian patent

The invention relates to DNA encoding a functional serotonin 5HT1c receptor, e.g. cDNA, and to the isolated, functional serotonin 5HT1c receptor encoded by such DNA. The invention also relates to mammalian cells expressing the cDNA encoding the 5HT1c receptor and to a DNA probe useful for detecting nucleic acid encoding the serotonin 5HT1c receptor. This invention provides methods for determining binding to the serotonin 5HT1c receptor, methods of detecting the expression and the presence of the serotonin 5HT1c receptor on the surface of a cell and to a method of screening drugs to identify drugs which specifically interact with, and bind to the serotonin 5HT1c receptor on the surface of …
