The life cycle of RNA is orchestrated by a series of molecular events whose dynamic regulation is central to gene expression and cellular function. However, existing methods face limitations in continuously recording these events in living cells. Here we introduce mTRACE (Modification-enabled Tracking of RNA-associated Cellular Events), a molecular recording framework that leverages RNA modification enzymes to capture the history of RNA-associated cellular processes. By systematically screening a pool of 34 candidate enzymes, we identified N6-adenosine methyltransferase M.EcoGII as a highly efficient and unbiased modifier. mTRACE exploits M.EcoGII to introduce natural and non-disruptive RNA modification, writing durable marks on transcripts undergoing specific molecular events. We demonstrate that mTRACE enables precise mapping of RNA-protein interactions, including tracking and retrospective detection of ALYREF binding; quantification of both translational activity and efficiency by coupling M.EcoGII to ribosomal proteins; and spatial recording of RNA residence across subcellular compartments using engineered M.EcoGII variants. mTRACE provides a powerful solution for dissecting RNA dynamic regulation and opens a new avenue for multi-dimensional recording of RNA biology with spatiotemporal resolution.
