Total RNA was extracted from rSeV-GFP or mock-infected A549 cells and subjected to sonication. RNA containing m6A methylation was pulled down by m6A antibody. Three replicates (n = 3) of RNA from virus-infected cells were m6A sequenced.
Nucleotide sequence position with reference to the Sendai virus Z strain expressing GFP (GenBank accession no. AB855655). Nucleotide ranges are indicated.
The SeV genes and GFP gene are covered by m6A peaks. These regions may contain m6A sites.
Log2 enrichment of the m6A peaks identified in the SeV antigenome and mRNAs.
Putative m6A sites are identified based on searching for the presence of the m6A motif Pu [G > A]m6AC[A/C/U] (where Pu represents purine) in the peak ranges.
