Abstract: This invention relates to the identification of LPA as a ligand for the G-protein coupled receptors OSGPR114 and OSGPR78. The invention is directed to new methods for screening candidate drugs for their ability to modulate the activity of OSGPR114 or OSGPR78, and new pharmaceutical agents identified by these methods. It is also directed to the use of such agents in the manufacture of medicaments for the treatment of OSGPR114 or OSGPR78 mediated diseases, and methods of treating diseases such as cancers by administering to an individual a therapeutic amount of a modulator of OSGPR114 or OSGPR78 identified by these methods.

Abstract: The present invention makes available a rapid, reproducible, robust assay system for screening and identifying pharmaceutically effective compounds that specifically interact with and modulate the activity of a cellular protein, e.g., a receptor. or ion channel. The subject assay enables rapid screening of large numbers of compounds to identify those which act as an agonist or antagonist to the bioactivity of the cellular protein. In this system, the first cell is treated with a compound, and functional interaction of this compound with a cellular receptor yields a secreted signal. A second cell, bearing a receptor for this secreted signal, makes use of an indicator gene in a signaling pathway coupled to this second receptor. The subject assays include methods of identifying compounds which specifically modulate, for example, heterologous receptors coupled to the pheromone response pathway in yeast.
