RNA modification

RNA modifications are changes to the chemical composition of ribonucleic acid (RNA) molecules post-synthesis that have the potential to alter function or stability. An example of RNA modification is the addition of a methylated guanine nucleotide “cap” to the 5’-end of messenger RNAs (mRNAs).

    Cytosine methylation (m5C) is one of the more disputed base modifications of the epitranscriptome, mostly because current methods for detection are prone to artifacts. A new approach to increase detection accuracy reveals intriguing evidence of a role for the tRNA methyltransferase NSUN2 in the methylation of mRNA.

    Recent advances in the ability to detect mRNA base modifications have led to a renewed appreciation for the diversity of the epitranscriptome and its ability to influence gene expression. Now, a study in Cell adds acetylated cytidine (ac4C) to the list, identifying it as a widespread mark in cellular mRNAs that influences both mRNA stability and translation.

    N6-methyladenosine (m6A) mRNA modification influences mRNA fate by stimulating recruitment of m6A reader proteins. A previously unappreciated class of m6A reader proteins is now shown to use a common RNA-binding domain and flanking regions to selectively bind m6A-containing mRNAs, increasing their translation and stability.
