Abstract:
The most prevalent modified base in mRNA, N6 -methyladenosine (m6 A), is found in several thousand transcripts, typically near the stop codon, although it can occur anywhere in the mRNA. In addition, the highly similar nucleotide N6 ,2'-O-dimethyladenosine (m6 Am), which is difficult to distinguish from m6 A, occurs as the first transcribed nucleotide of certain transcripts. Both the m6 A and m6 Am modifications have been implicated in numerous biological processes, and their precise mapping is crucial to understanding their functions. To address this need, we developed miCLIP, a method that maps both m6 A and m6 Am at individual nucleotide resolution. Here we describe the miCLIP protocol, with slight improvements to the initially published protocol for both the experimental methodology and bioinformatics analysis. © 2019 by John Wiley & Sons, Inc.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
