The present invention provides compositions and methods for capture and identification of the cellular targets of a bioactive agent. In particular, provided herein are bioactive agents tethered to capture ligand, cellular targets (optionally tagged with a reporter), capture proteins (optionally present as capture fusions), surfaces (e.g., displaying, capture ligands, capture proteins, or capture fusions), and methods of capturing and identifying the cellular targets of a bioactive agent therewith.
