The present invention provides a method of obtaining a composition which comprises determining whether a chemical compound binds to a human 5-HT receptor expressed on the surface of a mammalian cell transfected with a vector adapted for expressing the receptor in the cell, and if the compound binds to the receptor, admixing the compound with a carrier. The present invention further provides a method of obtaining a composition which comprises determining whether a chemical compound binds to and activates or binds to and inhibits activation of a human 5-HT receptor expressed on the surface of a mammalian cell, wherein the human 5-HT receptor is expressed on the surface of a mammalian cell transfected with a vector adapted for expressing the receptor in the cell, and if the compound binds to and activates or binds to and inhibits activation of the receptor, admixing the compound with a carrier.

Methods of obtaining compounds that interact with a human serotonin (5-HT2) receptor

The present invention provides an isolated nucleic acid molecule encoding a 5-HT.sub.2 receptor, and an isolated protein which is a human 5-HT.sub.2 receptor. The invention also provides vectors comprising DNA molecules encoding a human 5-HT.sub.2 receptor, and vectors adapted for expression of the 5-HT.sub.2 receptor in bacterial, yeast, or mammalian cells. In addition, the invention provides a DNA probe useful for detecting nucleic acid encoding the 5-HT.sub.2 receptor, a method for determining whether a ligand which is not known to be capable of binding to the 5-HT.sub.2 receptor can bind to the 5-HT.sub.2 receptor, a method for detecting the presence of 5-HT.sub.2 receptor on the surface of a cell, and a method of screening drugs to identify drugs which specifically interact with, and bind to, the 5-HT.sub.2 receptor. The invention herein also concerns an antibody directed to the human 5-HT.sub.2 receptor, such as a monoclonal antibody directed to an epitope of the 5-HT.sub.2 receptor present on the surface of a cell and having an amino acid sequence included within the amino acid sequence shown in FIGS. 2A-2G.
