Despite the nuclear localization of the mA machinery, the genomes of multiple exclusively-cytoplasmic RNA viruses, such as chikungunya (CHIKV) and dengue (DENV), are reported to be extensively mA-modified. However, these findings are mostly based on mA-Seq, an antibody-dependent technique with a high rate of false positives. Here, we address the presence of mA in CHIKV and DENV RNAs.

It modulates mRNA fate and dynamics to exert regulatory control over numerous cellular processes and disease pathways, including viral infection. Kaposi's sarcoma-associated herpesvirus (KSHV) reactivation from the latent phase leads to the redistribution of mA topology upon both viral and cellular mRNAs within infected cells.

Using an mA-modified hairpin present in the Kaposi's sarcoma associated herpesvirus (KSHV) RNA, we identified seven members from the 'Royal family' as putative mA readers, including SND1.
