N6-methyladenosine (m⁶A) constitutes the most prevalent nucleotide modification within eukaryotic messenger RNA (mRNA). Variations in m⁶A levels are associated with numerous human diseases and health conditions, including various forms of cancer, diabetes, neurological disorders, male infertility, and obesity. Nevertheless, the molecular mechanisms underpinning the recognition of m⁶A by different ‘reader’ proteins remain incompletely elucidated. In this study, we used phage display to identify key sequence features that methyl readers recognize in m⁶A. This study shows that m⁶A modifications affect the mRNA interactome. A peptide motif recognizing m⁶A in DRACH sequences suggests a common recognition mechanism, though proteins may use different methods to detect m⁶A in less accessible areas. The sequence of the hnRNP A1 RRM domain that aligns with the newly discovered m⁶A-binding peptide, m1p1, is crucial for the binding of m⁶A-modified RNAs, indicating a strong link between the m1p1 sequence and m⁶A recognition, which is key for recognizing m⁶A-modified, unstructured RNAs. Gaining a comprehensive understanding of the evolutionary influence of m⁶A on its reader proteins may facilitate the identification of additional m⁶A readers. These signature peptides could enhance theranostic approaches across cancers, enabling more targeted therapies.
