Regulation of alternative polyadenylation
Web2 days ago · Alternative splicing (AS) is an important process in gene regulation. It allows multiple mRNA transcripts to be produced from one pre-mRNA through the different combinations of splicing sites, contributing to the diversity of mature mRNA molecules in their localization, stability, and translation properties [].The proportion of multiexon protein … WebNov 25, 2024 · Polyadenylation of pre-messenger RNA (pre-mRNA) specific sites and termination of their downstream transcriptions are signaled by unique sequence motif …
Regulation of alternative polyadenylation

WebComparative functional genomic studies have shown that differences in gene expression between species can often be explained by corresponding inter-species differences in genetic and epigenetic regulatory mechanisms. In the quest to understand gene WebFunctioning as an essential step of pre-mRNA processing, polyadenylation has been realized in recent years to play an important regulatory role during eukaryotic gene expression. …
WebIts position can vary and alternative polyadenylation (APA) transcripts can exist for a gene. This causes variance in 3' regulatory domains and can affect coding sequence if intronic events occur. The distribution of polyA sites on articular chondrocyte transcripts has not been studied so we aimed to define their transcriptome-wide location in age-matched … WebDec 13, 2024 · Alternative polyadenylation (APA) generates transcript isoforms with different 3’ ends. Differences in polyadenylation sites usage, which have been associated with diseases like cancer, regulate mRNA stability, subcellular localization, and translation. By characterizing APA across the 24-hour day in mouse liver, here we show that rhythmic …
