Small-molecule metabolites regulate many cellular processes but are often present at low concentrations, confounding studies of their signaling networks. In this issue of Cell Chemical Biology, You et al. (2019) describe RNA “integrators” that measure the concentrations of metabolites in live cells to enable in-depth studies of signaling pathways.
