In summary, we demonstrate that that capped 3′UTR-derived RNAs arise from structured G-motif-rich regions bound by AGO2 and UPF1, and they localise separately from their parental mRNAs.

Using high-resolution imaging, we validated that 3′UTR-derived RNAs localise differently from their parental mRNAs within the cell, hinting at potential independent functions.

We also found that cytoplasmic capping can occur subsequent to AGO2/siRNA-mediated cleavage, by analysing FANTOM5 CAGE from siRNA-treated samples. Our findings demonstrate that capping can readily follow cytoplasmic cleavage, and is not exclusive to transcriptional initiation.

Our analysis shows that AGO2 binds upstream of 3′UTR-derived RNA start sites—independent of miRNA binding. Interestingly, G4 motifs influence the binding positions of both AGO2 and UPF1, shaping the capping sites.

By integrating AGO2-eiCLIP, eCLIP, and CAGE-seq, we found their origins linked to RNA-binding proteins, specifically AGO2 and UPF1. These sites are often rich in G-motifs capable of forming G-Quadruplexes.

CAGE profiling often reveals signals (~10-15%) in 3′UTRs — regions far from usual transcription start sites (TSS). This phenomenon is reproducible but poorly understood.
