title: A reverse transcriptase stop assay revealed diverse quadruplex formations in UTRs in mRNA.
abstract: Here, we developed a reverse transcriptase based method (RTase stop assay) to characterize quadruplex formations in guanine-rich RNAs with high sensitivity and specificity. By using the RTase stop assay, we also revealed a plausible structural polymorphism in biologically important RNAs. The RTase stop assay would provide helpful insight into RNA quadruplex structures and functions, together with other analytical methods, including various footprinting techniques.
