π Tender Overview
Mapping And Direct Sequencing Of The Non-Canonical Cap Code
From their creation to their degradation, mRNAs are under extensive regulation. This regulation is directed not only by their nucleotide sequence and their promoter but also by post- and co-transcriptional modifications attached to the RNA. One of the most ubiquitous of these modifications in eukaryotes is the 5' cap β typically a methylated guanine (m7G) attached inversely to the first transcribed nucleotide. Several decades of research have revealed the m7G cap as an interface for regulating stability, splicing, polyadenylation, localization, and translation. The m7G cap was long presumed to be the only functional cap in eukaryotes, but this view was recently overturned by the discovery of the non-canonical nicotinamide adenine dinucleotide (NAD+) cap. Following this, several other eukaryotic cap structures were discovered: NADH, flavin adenine dinucleotide (FAD), uridine diphosphate glucose (UDP-Glc), and uridine diphosphate N-acetylglucosamine (UDP-GlcNAc). The function of most non-canonical caps is unknown, but their presence suggests the existence of a regulatory cap code .
