摘要： The present invention makes available rapid, effective assays for screening and identifying pharmaceutically effective compounds that specifically interact with and modulate the activity of a cellular receptor or ion channel. The subject assays enable rapid screening of large numbers of polypeptides in a library to identify those polypeptides which induce or antagonize receptor bioactivity. The subject assays are particularly amenable for identifying agonists and antagonists for orphan receptors. In particular the present invention makes available novel ligand agonists of human formyl peptide receptor like-1 (FPRL-1) receptors. These novel ligand agonists are used in the assays of the invention to identify modulators of FPRL-1 receptor.

摘要： Yeast cells are engineered to express both a surrogate of a pheromone system protein (e.g., enzymes involved in maturation of α-factor, transporters of a-factor, pheromone receptors, etc.) and a potential peptide modulator of the surrogate, in such a manner that the inhibition or activation of the surrogate affects a screenable or selectable trait of the yeast cells. Various additional features improve the signal-to-noise ratio of the screening/selection system.

摘要： The present invention pertains to novel yeast cells which are useful for the expression of heterologous G protein coupled receptors. The yeast cells of the present invention can be used in screening assays which can be used to screen for modulators of G protein coupled receptors. Specifically, the invention provides novel yeast cells which express a heterologous G protein coupled receptor and mutant and/or chimeric G protein subunit molecules which serve to functionally integrate the heterologous into the pheromone signaling pathway of the yeast cell. The invention also provides for the expression of heterologous G protein coupled receptors which are functionally integrated into the yeast cell membrane using a yeast α factor leader sequence. Drug discovery assays using the subject yeast cells are also provided.
