Alternative polyadenylation diversifies post‐transcriptional regulation by selective RNA–protein interactions
Recent research has uncovered extensive variability in the boundaries of transcript isoforms, yet the functional consequences of this variation remain largely unexplored. Here, we systematically discriminate between the molecular phenotypes of overlapping coding and non-coding transcriptional events from each genic locus using a novel genome-wide, nucleotide-resolution technique to quantify the...
متن کاملEvolution of Hox post-transcriptional regulation by alternative polyadenylation and microRNA modulation within 12 Drosophila genomes.
Hox genes encode a family of transcriptional regulators that operate differential developmental programs along the anteroposterior axis of bilateral animals. Regulatory changes affecting Hox gene expression are believed to have been crucial for the evolution of animal body plans. In Drosophila melanogaster, Hox expression is post-transcriptionally regulated by microRNAs (miRNAs) acting on targe...
متن کاملTranscriptional activity regulates alternative cleavage and polyadenylation
Genes containing multiple pre-mRNA cleavage and polyadenylation sites, or polyA sites, express mRNA isoforms with variable 3' untranslated regions (UTRs). By systematic analysis of human and mouse transcriptomes, we found that short 3'UTR isoforms are relatively more abundant when genes are highly expressed whereas long 3'UTR isoforms are relatively more abundant when genes are lowly expressed....
متن کاملRegulation of alternative polyadenylation by genomic imprinting.
Maternally and paternally derived alleles can utilize different promoters, but allele-specific differences in cotranscriptional processes have not been reported. We show that alternative polyadenylation sites at a novel murine imprinted gene (H13) are utilized in an allele-specific manner. A differentially methylated CpG island separates polyA sites utilized on maternal and paternal alleles, an...
متن کاملAlternative polyadenylation: new insights from global analyses.
Recent studies have revealed widespread mRNA alternative polyadenylation (APA) in eukaryotes and its dynamic spatial and temporal regulation. APA not only generates proteomic and functional diversity, but also plays important roles in regulating gene expression. Global deregulation of APA has been demonstrated in a variety of human diseases. Recent exciting advances in the field have been made ...
