(A) ecircRNAs (a) and eicircRNAs (b) are produced by back‐splicing. Clustering analysis using the 5000 top varying transcripts (Supplementary file 3.1) showed that the microsome and MBP fractions clustered together and the cytosol and FP fractions clustered together (Figure 3A). Crossref. We performed ribosome-protected fragment sequencing (ribo-seq) with MBPs. (C) Composition of sRNAs in three size classes in various samples. Recently, the antiviral role of AGO2 was confirmed for some RNA viruses that encode suppressors specifically targeting AGO1 . This analysis revealed higher numbers of hyper (MBP>TP) than hypo (MBP
