Rapid nuclear deadenylation of mammalian messenger RNA
MicroRNAs comprise 1-3% of all vertebrate genes, but their in vivo functions and mechanisms of action remain largely unknown. Zebrafish miR-430 is expressed at the onset of zygotic transcription and regulates morphogenesis during early development. Using a microarray approach and in vivo target vali...

Poly(A)-tail length and mRNA deadenylation play important roles in post-transcriptional gene regulation. Here, we report the regulation of mRNA expression, half-life, and polysome association in mouse embryonic stem cells by the Cnot3 subunit in the Ccr4-Not mRNA deadenylase complex. To determine th...

miRNAs silence gene expression by repressing translation and/or by promoting mRNA decay. AGO1 is a key protein required for miRNA-mediated gene silencing. In animal cells, mRNA degradation of partially complementary miRNA targets occurs via deadenylation by the CAF1-CCR4-NOT1 deadenylase complex, fo...
ORGANISM(S): Drosophila melanogaster 
Poly(A) tails protect RNAs from degradation and deadenylation rates determine RNA stability. Deadenylation has mostly been investigated within the cytoplasm and the dynamics of poly(A) tail length after transcription are not well understood. Combining long-read sequencing with metabolic labeling and...
