Experimental Genome-Wide Determination of RNA Polyadenylation in Chlamydomonas reinhardtii. [PDF]

PLoS ONE, 2016
The polyadenylation of RNA is a near-universal feature of RNA metabolism in eukaryotes. This process has been studied in the model alga Chlamydomonas reinhardtii using low-throughput (gene-by-gene) and high-throughput (transcriptome sequencing ...

U1 snRNP-Dependent Suppression of Polyadenylation: Physiological Role and Therapeutic Opportunities in Cancer

International Journal of Cell Biology, 2013
Pre-mRNA splicing and polyadenylation are critical steps in the maturation of eukaryotic mRNA. U1 snRNP is an essential component of the splicing machinery and participates in splice-site selection and spliceosome assembly by base-pairing to the 5 ...

Cellular stress alters 3′UTR landscape through alternative polyadenylation and isoform-specific degradation

Nature Communications, 2018
Most eukaryotic genes express alternative polyadenylation (APA) isoforms with different 3′UTR lengths, production of which is influenced by cellular conditions.

The RNA Binding Protein Bcas2 is Required for Antibody Class Switch in Activated‐B Cells

Exploration, EarlyView.
Bcas2 recruits DHX15 and SRSF7 to form a protein complex for the splicing of CSR‐related mRNA at the 5' ss and 3' ss, generating two mature mRNA isoforms, which are ultimately translated into CSR‐related proteins. These CSR‐related proteins bind to DNA associated with antibodies, affecting the DSB repair of the relevant DNA after AID induction, thereby

PolyA_DB 3 catalogs cleavage and polyadenylation sites identified by deep sequencing in multiple genomes

Nucleic Acids Res., 2017
PolyA_DB is a database cataloging cleavage and polyadenylation sites (PASs) in several genomes. Previous versions were based mainly on expressed sequence tags (ESTs), which had a limited amount and could lead to inaccurate PAS identification due to the ...

Exploring the Impact of Cleavage and Polyadenylation Factors on Pre-mRNA Splicing Across Eukaryotes

G3: Genes, Genomes, Genetics, 2017
In human, mouse, and Drosophila, the spliceosomal complex U1 snRNP (U1) protects transcripts from premature cleavage and polyadenylation at proximal intronic polyadenylation signals (PAS).

Impact of Acute Endurance Exercise on Alternative Splicing in Skeletal Muscle

FASEB BioAdvances, EarlyView.
Current model on the effects of acute endurance exercise on the AS regulatory mechanism with key trans‐factors/RBPs (e.g., hnRNP‐A1, ‐A3, and TIA1). ABSTRACT Alternative splicing (AS) is a highly conserved posttranscriptional mechanism, generating mRNA variants to diversify the proteome.

Alternative polyadenylation allows differential negative feedback of human miRNA miR-579 on its host gene ZFR. [PDF]

PLoS ONE, 2015
About half of the known miRNA genes are located within protein-coding host genes, and are thus subject to co-transcription. Accumulating data indicate that this coupling may be an intrinsic mechanism to directly regulate the host gene's expression ...
