RNA MODIFICATION

Acetylation takes aim at 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.
