Annotation of polyadenylation sites from short-read RNA sequencing alone is a challenging computational task. Other algorithms rooted in DNA sequence predict potential polyadenylation sites; however, in vivo expression of a particular site varies based ...

N6-methyladenosine (m6A) is enriched in 3′untranslated region (3′UTR) and near stop codon of mature polyadenylated mRNAs in mammalian systems and has regulatory roles in eukaryotic mRNA transcriptome switch.

Nuclear polyadenylation factors recognize cytoplasmic polyadenylation elements. [PDF]
In the cytoplasm of oocytes and early embryos, addition of poly(A) to mRNAs can activate their translation. We demonstrate that despite many differences between poly(A) addition in the cytoplasm and nucleus, these two forms of polyadenylation may involve identical trans-acting factors.

Mechanisms of mRNA polyadenylation
mRNA 3'-end processing involves the addition of a poly(A) tail based on the recognition of the poly(A) signal and subsequent cleavage of the mRNA at the poly(A) site. Alternative polyadenylation (APA) is emerging as a novel mechanism of gene expression regulation in normal and in disease states.

Maturation of selected human mitochondrial tRNAs requires deadenylation
Human mitochondria contain a genome (mtDNA) that encodes essential subunits of the oxidative phosphorylation system. Expression of mtDNA entails multi-step maturation of precursor RNA. In other systems, the RNA life cycle involves surveillance mechanisms,

The N6-methyladenosine (m6A) modification is the most prevalent internal RNA modification in eukaryotes. The majority of m6A sites are found in the last exon and 3’ UTRs.

In mammalian species, both the maturation promoting factor (MPF) and the mitogen-activated protein kinase (MAPK) cascade play critical roles in modulating oocyte meiotic cell-cycle progression. MPF is a critical heterodimer composed of CDK1 and cyclin B1.
