Connections between mRNA 3' end processing and transcription termination.
Discoveries within the last few years have revealed that the multiple steps in gene expression are remarkably integrated. There have recently been several advances in deciphering how mRNA 3' end processing is linked with transcription elongation and termination. It has been known for quite a long time that transcription termination is somehow intertwined with polyadenylation, but it is still un...
متن کاملMolecular mechanisms of eukaryotic pre-mRNA 3′ end processing regulation
Messenger RNA (mRNA) 3' end formation is a nuclear process through which all eukaryotic primary transcripts are endonucleolytically cleaved and most of them acquire a poly(A) tail. This process, which consists in the recognition of defined poly(A) signals of the pre-mRNAs by a large cleavage/polyadenylation machinery, plays a critical role in gene expression. Indeed, the poly(A) tail of a matur...
متن کاملCoordination between transcription and pre-mRNA processing.
A large body of work has proved that transcription by RNA polymerase II and pre-mRNA processing are coordinated events within the cell nucleus. Capping, splicing and polyadenylation occur while transcription proceeds, suggesting that RNA polymerase II plays a role in the regulation of these events. The presence and degree of phosphorylation of the carboxy-terminal domain of RNA polymerase II la...
متن کاملSpatial Organization and Dynamics of Transcription Elongation and Pre-mRNA Processing in Live Cells
During the last 30 years, systematic biochemical and functional studies have significantly expanded our knowledge of the transcriptional molecular components and the pre-mRNA processing machinery of the cell. However, our current understanding of how these functions take place spatiotemporally within the highly compartmentalized eukaryotic nucleus remains limited. Moreover, it is increasingly c...
متن کاملStructure and Function of Pre-mRNA 5′-End Capping Quality Control and 3′-End Processing
Messenger RNA precursors (pre-mRNAs) are produced as the nascent transcripts of RNA polymerase II (Pol II) in eukaryotes and must undergo extensive maturational processing, including 5'-end capping, splicing, and 3'-end cleavage and polyadenylation. This review will summarize the structural and functional information reported over the past few years on the large machinery required for the 3'-en...
