M6A reader CPSF70 controls polyadenylation site choice through m6A-dependent recognition of FUE polyadenylation signal

ABSTRACT: We conduct herein a systematic study of mRNA recognition and consequent polyadenylation processing of the Arabidopsis mRNA by m6A reader protein CPSF70. Transcriptome-wide characterization of CPSF70-binding sites supporting the recognition m6A-methylated mRNA with CPSF70, and the results of which linked polyadenylation signals recognition. We then perform 3’end sequencing with A-seq2 to identify CPSF70-dependent APA process, showing that CPSF70 modulate m6A–dependent polyadenylation with FUE recognition.
