The Role of E6 Spliced Isoforms (E6*) in Human Papillomavirus-Induced Carcinogenesis
Viruses, 2018 Persistent infections with High Risk Human Papillomaviruses (HR-HPVs) are the main cause of cervical cancer development. The E6 and E7 oncoproteins of HR-HPVs are derived from a polycistronic pre-mRNA transcribed from an HPV early promoter.

Unleashing the potential of catalytic RNAs to combat mis-spliced transcripts
Frontiers in Bioengineering and Biotechnology, 2023 Human transcriptome can undergo RNA mis-splicing due to spliceopathies contributing to the increasing number of genetic diseases including muscular dystrophy (MD), Alzheimer disease (AD), Huntington disease (HD), myelodysplastic syndromes (MDS).

Saturation mutagenesis reveals manifold determinants of exon definition. [PDF]
, 2017 To illuminate the extent and roles of exonic sequences in the splicing of human RNA transcripts, we conducted saturation mutagenesis of a 51-nt internal exon in a three-exon minigene.

Introns: the “dark matter” of the eukaryotic genome
Frontiers in Genetics, 2023 The emergence of introns was a significant evolutionary leap that is a major distinguishing feature between prokaryotic and eukaryotic genomes. While historically introns were regarded merely as the sequences that are removed to produce spliced ...

The CUGBP2 splicing factor regulates an ensemble of branchpoints from perimeter binding sites with implications for autoregulation [PDF]
, 2009 Alternative pre-mRNA splicing adjusts the transcriptional output of the genome by generating related mRNAs from a single primary transcript, thereby expanding protein diversity.

Prespliceosome structure provides insights into spliceosome assembly and regulation
Nature, 2018 The spliceosome catalyses the excision of introns from pre-mRNA in two steps, branching and exon ligation, and is assembled from five small nuclear ribonucleoprotein particles (snRNPs; U1, U2, U4, U5, U6) and numerous non-snRNP factors1.

Mechanism of spliceosome remodeling by the ATPase/helicase Prp2 and its coactivator Spp2
Science, 2020 Remodeling an RNA processing machine Splicing of precursor messenger RNA (pre-mRNA) is carried out by the spliceosome, a highly dynamic, supramolecular complex that undergoes assembly, activation, catalysis, and disassembly.

Can we always sweep the details of RNA-processing under the carpet?
, 2013 RNA molecules follow a succession of enzyme-mediated processing steps from transcription until maturation. The participating enzymes, for example the spliceosome for mRNAs and Drosha and Dicer for microRNAs, are also produced in the cell and their copy ...
