METHODS AND KITS FOR IDENTIFYING A PROTEIN ASSOCIATED WITH RECEPTOR-LIGAND INTERACTIONS

摘要

A method for identifying a protein associated with a receptor-ligand interaction is described. The method comprises providing a population of engineered cells comprising a targeting library targeting specific gene expression, contacting the population of cells with a recombinant toxin fusion for sufficient time, and identifying proteins in the selection pool of cells by sequencing one or more of the nucleic acid molecule comprised in the selection pool of cells, thereby identifying the target gene. Toxin-resistant cell lines, toxin-producing cell lines, recombinant toxin fusions, probes and methods producing same, and kits thereof, are also provided.
