A⁶A-seq: N ⁶-allyladenosine-based cellular messenger RNA metabolic labelling and sequencing.

ABSTRACT: The integration of RNA metabolic labelling by nucleoside analogues with high-throughput RNA sequencing has been harnessed to study RNA dynamics. The immunoprecipitation purification or chemical pulldown technique is generally required to enrich the analogue-labelled RNAs. Here we developed an a⁶A-seq method, which takes advantage of N⁶-allyladenosine (a⁶A) metabolic labelling on cellular mRNAs and profiles them in an immunoprecipitation-free and mutation-based manner. a⁶A plays a role as a chemical sequencing tag in that the iodination of a⁶A in mRNAs results in 1,N ⁶-cyclized adenosine (cyc-A), which induces base misincorporation during RNA reverse transcription, thus making a⁶A-labelled mRNAs detec
