Understanding splicing regulation through RNA splicing maps
Alternative splicing is a highly regulated process that greatly increases the proteome diversity and plays an important role in cellular differentiation and disease. Interactions between RNA-binding proteins (RBPs) and pre-mRNA are the principle regulator of splicing decisions.

Group I self-splicing intron constitutes an important class of functional RNA molecules that can promote chemical transformation. Although the fundamental mechanism of the auto-excision from its precursor RNA has been established, convenient assay ...

Writing a wrong: Coupled RNA polymerase II transcription and RNA quality control [PDF]
Processing and maturation of precursor RNA species is coupled to RNA polymerase II transcription. Co-transcriptional RNA processing helps to ensure efficient and proper capping, splicing, and 3' end processing of different RNA species to help ensure ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Catalytic RNA and RNA Splicing [PDF]
The capacity of Watson-Crick base-pair complementarity to direct informational transactions basic to gene expression has long been appreciated. Among RNA molecules, it mediates mRNA-tRNA codon-anticodon pairing and the 16S rRNA-mRNA Shine-Dalgarno interaction.

Structural insights into RNA splicing [PDF]
Intron splicing is a fundamental biological process whereby noncoding sequences are removed from precursor RNAs. Recent work has provided new insights into the structural features and reaction mechanisms of two introns that catalyze their own splicing from precursor RNA: the group I and II introns.

A unified mechanism for intron and exon definition and back-splicing. [PDF]
The molecular mechanisms of exon definition and back-splicing are fundamental unanswered questions in pre-mRNA splicing. Here we report cryo-electron microscopy structures of the yeast spliceosomal E complex assembled on introns, providing a view of the ...

Interaction of yeast eIF4G with spliceosome components Implications in pre-mRNA processing events [PDF]
International audienceAs evidenced from mammalian cells the eukaryotic translation initiation factor eIF4G has a putative role in nuclear RNA metabolism. Here we investigate whether this role is conserved in the yeast Saccharomyces cerevisiae.

The newfound relationship between extrachromosomal DNAs and excised signal circles
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
