Mechanism and regulation of mRNA polyadenylation.
A poly(A) tail is found at the 38 end of nearly every fully processed eukaryotic mRNA and has been suggested to influence virtually all aspects of mRNA metabolism. Its proposed functions include conferring mRNA stability, promoting an mRNA’s translational efficiency, and having a role in transport of processed mRNA from the nucleus to the cytoplasm (for recent reviews, see Lewis et al. 1995; Sa...
متن کاملChromatin and epigenetic regulation of pre-mRNA processing.
New data are revealing a complex landscape of gene regulation shaped by chromatin states that extend into the bodies of transcribed genes and associate with distinct RNA elements such as exons, introns and polyadenylation sites. Exons are characterized by increased levels of nucleosome positioning, DNA methylation and certain histone modifications. As pre-mRNA splicing occurs co-transcriptional...
متن کاملCharacterization of the Distal Polyadenylation Site of the ß-Adducin (Add2) Pre-mRNA
Most genes have multiple polyadenylation sites (PAS), which are often selected in a tissue-specific manner, altering protein products and affecting mRNA stability, subcellular localization and/or translability. Here we studied the polyadenylation mechanisms associated to the beta-adducin gene (Add2). We have previously shown that the Add2 gene has a very tight regulation of alternative polyaden...
متن کاملThe end of the message: multiple protein-RNA interactions define the mRNA polyadenylation site.
The key RNA sequence elements and protein factors necessary for 3' processing of polyadenylated mRNA precursors are well known. Recent studies, however, have significantly reshaped current models for the protein-RNA interactions involved in poly(A) site recognition, painting a picture more complex than previously envisioned and also providing new insights into regulation of this important step ...
متن کاملTranscriptome-wide analyses of CstF64-RNA interactions in global regulation of mRNA alternative polyadenylation.
Cleavage stimulation factor 64 kDa (CstF64) is an essential pre-mRNA 3' processing factor and an important regulator of alternative polyadenylation (APA). Here we characterized CstF64-RNA interactions in vivo at the transcriptome level and investigated the role of CstF64 in global APA regulation through individual nucleotide resolution UV crosslinking and immunoprecipitation sequencing and dire...
