Post-transcriptional 3’UTR cleavage of mRNA transcripts generates thousands of stable uncapped autonomous RNA fragments

ABSTRACT: Here, using genome wide analysis, we demonstrate that canonical mRNA is processed post-transcriptionally through an alternative cleavage and polyadenylation mechanism. As a result of this process, the downstream cleavage fragment of the 3′UTR remains uncapped and stable This finding indicates that different parts of gene mRNA are separate and independent, by re-annotating the human transcriptome using this model, we provide a new overview of the function and impact of microRNA (miRNA) Our results shed new light on the mammalian transcriptome and show that what were considered as 3′UTRs are in fact autonomous RNA fragments.

Alternative cleavage and polyadenylation generates downstream uncapped RNA isoforms with translation potential

Project description:Here, we uncovered the expression of thousands of previously unnoticed 5’-Uncapped and Polyadenylated Transcripts (5’UPTs). We show that 5’UPTs appear downstream of APA points that occur within the coding and intronic regions of their host genes. Furthermore, 5’UPTs are marked with N6-methyladenosine (m6A) at their 5’ termini, and this modification is linked to their expression. We also demonstrate that 5’UPTs are strongly enriched in polysomal RNA fractions, suggesting protein production capacity. In addition, we examined the expression of 5’UPTs in the biological context of T cell activation, known to induce APA usage. In line with a causal link between APA and 5’UPTs, T cell activation induced 5’UPTs expression and their incorporation into heavy polysomal fractions. Our findings indicate that APA does not only generates shorter upstream mRNA isoforms, but is also responsible for the generation of downstream uncapped and polyadenylated transcripts that possess potential translational capacity.

Cleavage Factor Im as a key regulator of 3’ UTR length

Project description:In eukaryotes, the 3' ends of RNA polymerase II-generated transcripts are made in the majority of cases by site-specific endonucleolytic cleavage, followed by the addition of a poly(A) tail. By alternative polyadenylation, a gene can give rise to multiple mRNA isoforms that differ in the length of their 3' UTRs and hence in their susceptibility to post-transcriptional regulatory factors such as microRNAs. A series of recently conducted high-throughput studies of poly(A) site usage revealed an extensive tissue-specific control of 3’ UTR length and drastic changes in 3’ UTR length of mRNAs upon induction of proliferation in resting cells. To understand the dynamics of polyadenylation site usage, we recently identified binding sites of the major pre-mRNA 3’ end processing factors - cleavage and polyadenylation specificity factor (CPSF), cleavage stimulation factor (CstF), and cleavage factor Im (CF Im) - and mapped cleaved polyadenylation sites in HEK293 cells. Our present study extends previous findings on the role of CF Im in alternative polyadenylation and reveals that subunits of the CF Im complex generally control 3’ UTR length. More specifically, we demonstrate that the loss-of-function of CF Im68 and CF Im25 but not of CF Im59 leads to a transcriptome-wide increase of the use of proximal polyadenylation sites. 3' ends of transcripts were profiled by high-throughput sequencing in HEK 293 cells under normal conditions, and in HEK 293 cells depleted of 3' end processing factors CF Im25, CF Im59, and CF Im68.

A global profiling of uncapped mRNAs under cold stress reveals specific decay patterns and endonucleolytic cleavages in Brachypodium

Project description:PARE (parallel analysis of RNA ends) was performed to study the change of uncapped mRNAs before and after cold treatment in Brachypodium. Different change patterns were identified. We have provided a complete view of uncapped transcriptome under cold stress condition, which will deepen our understanding of gene expression regulation in cold stress response as well as cold stress response mechanism for monocot plants. The uncapped mRNA profiles of 12-day-old Brachypodium seedlings with and without cold treatment (4 M-BM-0C for 24 h) were generated by deep sequencing using Illumina GAIIx

Cytoplasmic cleavage of IMPA1 3’UTR is necessary for maintaining axon integrity.

Project description:The 3’ untranslated regions (3’UTRs) of messenger RNAs (mRNA) are non-coding sequences involved in many aspects of mRNA metabolism, including intracellular localisation and translation. Incorrect processing and delivery of mRNA causes severe developmental defects and has been implicated in many neurological disorders. Here, we use deep sequencing to show that in sympathetic neuron axons, the 3’UTRs of many transcripts undergo cleavage, generating isoforms that express the coding sequence with a short 3’UTR, and stable 3’UTR-derived fragments of unknown function. Cleavage of the long 3’UTR of Inositol Monophosphatase 1 ( IMPA1 ), mediated by a protein complex containing the endonuclease Ago2 and the RNA binding protein HuD, generates a translatable isoform that is necessary for maintaining the integrity of sympathetic neuron axons. Thus, our study provides a new mechanism of mRNA metabolism that simultaneously regulates local protein synthesis and generates a yet undescribed class of non-coding RNAs.

Calpain Cleavage of Junctophilin-2 generates a Spectrum of Calcium-dependent Cleavage Products and DNA-rich NT1-Fragment Domains in Cardiomyocytes

Project description:Calpains are calcium (Ca2+) activated neutral proteases that are involved in several essential signaling pathways. One Calpain-specific proteolytic target is Junctophilin-2 (JP2), an important structural protein of Ca2+ release units required for the excitation-contraction coupling in cardiomyocytes. While downregulation of JP2 by Calpain cleavage in mouse models of heart failure has been reported previously, the precise molecular identity of the Calpain cleavage sites and the (patho-) physiological roles of the JP2 proteolytic products remain controversial. We systematically analyzed the JP2 cleavage fragments as function of Calpain-1 versus Calpain-2 proteolytic activities, revealing that both Calpain isoforms preferentially cleave mouse JP2 at R565 but subsequently also at three additional secondary Calpain cleavage sites. We identified the Calpain-specific primary cleavage products not only in mouse but also in human iPSC-derived cardiomyocytes (hiPSC-CMs). Knockout of RyR2 in hiPSC-CMs destabilized JP2 resulting in an increase of the Calpain-specifc cleavage fragments. The primary N-terminal cleavage product (NT1) accumulated in the nucleus of mouse and human cardiomyocytes in a Ca2+ dependent manner, closely associated with DNA-rich chromosomal regions, where NT1 is proposed to function as a cardioprotective transcriptional regulator in heart failure. Taken together, our data suggest that stabilizing NT1 by preventing secondary cleavage events by Calpain and other proteases could be an important therapeutic target for future studies.
