Project description:Complex organisms are able to generate differential gene expression through the same set of DNA sequences in distinct cells. The communication between chromatin and RNA regulates how cells behave in tissues. However, little is known about how chromatin, especially the histone modifications, regulates RNA polyadenylation. Here, we find that FUS is recruited to chromatin by H3K36me3 at gene bodies. Once H3K36me3 is abolished, FUS is dissociated from chromatin to increase the binding with RNA, resulting in increased distal polyadenylation selections that are far from the stop codon. The H3K36me3 recognition of FUS is mediated by the proline residues in ZNF domain, mutations of which lead to reduced chromatin association of FUS, increased RNA binding of FUS, and distal polyadenylation selections. Proline mutation, which corresponds to the mutation in amyotrophic lateral sclerosis, contributes to the hyperactivation of mitochondria and hyperdifferentiation in mouse embryonic stem cells. These findings reveal FUS as an H3K36me3 reader protein that links chromatin-mediated alternative polyadenylation to human disease.

Project description:Analogous to alternative splicing, alternative polyadenylation (APA) has long been thought to result from competition between proximal and distal polyA sites. By Fractionation-seq, we unexpectedly identified several hundred APA genes where their distal polyA isoforms are retained in chromatin/nuclear matrix and proximal polyA isoforms released into the cytoplasm. Global metabolic PAS-seq and Nanopore long-read RNA-seq provided further evidence that the strong distal polyA sites are first processed and the resulting transcripts are anchored in chromatin/nuclear matrix for further processing at proximal polyA sites and removal of certain slowly spliced introns. By engineering an autocleavable ribozyme between the proximal and distal polyA sites, we demonstrated that the distal polyA isoform is indeed the precursor to the proximal polyA isoform. Therefore, unlike alternative splicing, APA sites are recognized independently, rather than competitively, and in many cases, in a sequential manner. This provides a versatile strategy to regulate gene expression in mammalian cells.

Project description:Genes containing multiple polyadenylation (polyA) sites express mRNA isoforms with variable 3’ untranslated regions (3’UTRs). We found that short and long 3’UTR isoforms were relatively more abundant when genes were highly and lowly expressed, respectively, in human and mouse cells. Consistently, upregulated and downregulated genes were more likely to have shortened and lengthened 3’UTRs, respectively, when genes changed expression under different cell conditions or in response to extracellular stimuli. Using nuclear run-on assays, we found that RNA polymerase II (Pol II) was more likely to pause at the polyA site of highly expressed genes than that of lowly expressed ones. Moreover, in line with the difference in polyA site usage, highly expressed genes tend to have higher H3K4me3 and H3K36me3 levels but a lower density of nucleosome around promoter-proximal polyA sites relative to distal ones. Taken together, our results indicate that the efficiency of 3’ end processing is generally coupled to transcriptional activity, leading to modulation of polyA site choice by transcription and thus connecting transcriptional control with post-transcriptional regulation via pre-mRNA processing.
