A geneticallyencoded trifunctional photocrosslinker was developed that bears a bioorthogonal handle and a releasable linker in addition to its photoaffinity warhead. This probe enabled the enrichment of transient and low-abundance prey proteins after intracellular photocrosslinking and prey–bait separation. A quantitative and comparative proteomic strategy using this probe revealed the substrates of
