This invention provides isolated nucleic acid molecules encoding Y2 receptors, an isolated, purified Y2 receptor protein, vectors comprising isolated nucleic acid molecules encoding Y2 receptors, mammalian, insect, bacterial and yeast cells comprising such vectors, antibodies directed to the Y2 receptors, nucleic acid probes useful for detecting nucleic acid encoding Y2 receptors, antisense oligonucleotides complementary to unique sequences of a nucleic acid molecule which encodes a Y2 receptor, pharmaceutical compounds related to the Y2 receptors, and nonhuman transgenic animals which express nucleic acid encoding a normal or mutant Y2 receptor. This invention further provides methods for determining ligand binding, detecting expression, drug screening, and methods of treatment involving Y2 receptors.

Method of obtaining compositions comprising Y2 specific compounds

The present invention provides a process for identifying a chemical compound which specifically binds to a rat or human 5-HT,receptor. The invention also provides a process involving competitive binding for identifying a chemical compound which specifically binds to a rat or human 5-HT,receptor. The invention provides for a process for determining whether a chemical compound specifically binds to and activates a rat or human 5-HT,receptor. The invention additionally provides for a process for determining whether a chemical compound specifically binds to and inhibits activation of a rat or human 5-HT,receptor.

Uses of the 5-HT4 receptor

This invention provides methods of modifying feeding behavior, including increasing or decreasing food consumption, e.g., in connection with treating obesity, bulimia or anorexia. These methods involve administration of compounds that are selective agonists or antagonists for the Y5 receptor. One such compound has the structure: ##STR1## In addition, this invention provides an isolated nucleic acid molecule encoding a Y5 receptor, an isolated Y5 receptor protein, vectors comprising an isolated nucleic acid molecule encoding a Y5 receptor, cells comprising such vectors, antibodies directed to the Y5 receptor, nucleic acid probes useful for detecting nucleic acid encoding Y5 receptors, antisense oligonucleotides complementary to any unique sequences of a nucleic acid molecule which encodes a Y5 receptor, and nonhuman transgenic animals which express DNA encoding a normal or a mutant Y5 receptor.
