A c-Myc-transcribed long noncoding RNA namely LAST (LncRNA-assisted stabilization of transcripts) collaborates with a cellular factor CNBP to promote the stability of CCND1/cyclin D1 mRNA post-transcriptionally, ensuring the proper G1/Sphase transition of the cell cycle.
Genomic-profiles and reporters reveal that the three-nucleotide ‘words’ read by the ribosome, codons, have a strong effect on mRNA stability, impacting the homeostatic mRNA and protein levels in human cells.
Interaction with PUMILIO is essential for maintenance of genomic stability by the cytoplasmic long noncoding RNA NORAD, whereas binding to RBMX is dispensable for this function.
Selective degradation of mature miRNAs shapes temporal miRNA expression patterns and is important for proper regulation of target genes to support normal development of Drosophila embryos.
When a protein involved in DNA repair malfunctions, it can anneal RNA molecules to DNA molecules, creating hybrids that increase the frequency of mutations in the DNA.
Non-invasive mRNA stability measurements reveal that transcript lifetime is governed by a competition with translation initiation on a transcriptome-wide level.
Phosphorylation of tyrosine 1 in the carboxy-terminal domain (CTD) of the largest subunit of RNA Polymerase (RNAP) II functions to stabilize this domain, and facilitates turnover of upstream antisense RNAs.
Structural and functional analyses show how the spliceosomal Prp3 protein concomitantly binds double- and single- stranded regions in U4/U6 di-snRNAs and serves to stabilize the U4/U6•U5 tri-snRNP for splicing.
A unique form of regulation has been observed in the unfolded protein response of S. pombe, along with a novel mechanism of post-transcriptional mRNA processing.
The crystal structure of Thermus transcription activation complexes containing the transcriptional activator CarD reveals a new mechanism for the activation of transcription.
