Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>N⁶‐methyladenosine (m⁶A) is an abundant internal modification in eukaryotic mRNA and plays regulatory roles in mRNA metabolism. However, methods to precisely locate the m⁶A modification remain limited. We present here a photo‐crosslinking‐assisted m⁶A sequencing strategy (PA‐m⁶A‐seq) to more accurately define sites with m⁶A modification. Using this strategy, we obtained a high‐resolution map of m⁶A in a human transcriptome. The map resembles the general distribution pattern observed previously, and reveals new m⁶A sites at base resolution. Our results provide insight into the relationship between the methylation regions and the binding sites of RNA‐binding proteins.</p> </abstract>
