tRNA splicing [PDF]

open access: yesJournal of Biological Chemistry, 1998
Introns interrupt the continuity of many eukaryal genes, and therefore their removal by splicing is a crucial step in gene expression. Interestingly, even within Eukarya there are at least four splicing mechanisms.

Spliced leader trans-splicing [PDF]

open access: yesCurrent Biology, 2006
What is spliced leader (SL) trans-splicing? It is an mRNA maturation process, similar to intron splicing, which has been shown to occur in a limited number of eukaryotes. In SL trans-splicing, the cell replaces nucleotides at the 5′ end of some pre-mRNAs with those of a special class of small nuclear RNAs, called SL RNAs. These are short molecules with

Altered splicing of ATG16‐L1 mediates acquired resistance to tyrosine kinase inhibitors of EGFR by blocking autophagy in non‐small cell lung cancer

open access: yesMolecular Oncology, 2022
Despite the initial efficacy of using tyrosine kinase inhibitors of epidermal growth factor receptors (EGFR‐TKIs) for treating patients with non‐small cell lung cancer (NSCLC), resistance inevitably develops.

Structural basis of intron selection by U2 snRNP in the presence of covalent inhibitors

open access: yesNature Communications, 2021
Chemical modulation of intron selection has emerged as a route for cancer therapy. Here, structures of the U2 snRNP’s SF3B module and of prespliceosome- both in complexes with splicing modulators- provide insight into the mechanisms of intron recognition

Spliceostatin C, a component of a microbial bioherbicide, is a potent phytotoxin that inhibits the spliceosome

open access: yesFrontiers in Plant Science, 2023
Spliceostatin C (SPC) is a component of a bioherbicide isolated from the soil bacterium Burkholderia rinojensis. The chemical structure of SPC closely resembles spliceostatin A (SPA) which was characterized as an anticancer agent and splicing inhibitor ...

UGT1A1 Variants c.864+5G>T and c.996+2_996+5del of a Crigler-Najjar Patient Induce Aberrant Splicing in Minigene Assays

open access: yesFrontiers in Genetics, 2020
A large fraction of DNA variants impairs pre-mRNA splicing in human hereditary disorders. Crigler-Najjar syndrome (CNS) is characterized by a severe unconjugated hyperbilirubinemia caused by variants in the UGT1A1 gene.

Splicing Misplaced [PDF]

open access: yesCell, 2005
Newly synthesized transcripts are usually spliced during transcription or immediately thereafter. So pre-mRNA splicing has been presumed to occur exclusively in the cell nucleus. In this issue of Cell, Denis et al. (2005) now report the presence of functional spliceosomes and signal-dependent pre-mRNA splicing in the cytoplasm of platelets.

The Expression Level of HIV-1 Vif Is Optimized by Nucleotide Changes in the Genomic SA1D2prox Region during the Viral Adaptation Process

open access: yesViruses, 2021
HIV-1 Vif plays an essential role in viral replication by antagonizing anti-viral cellular restriction factors, a family of APOBEC3 proteins. We have previously shown that naturally-occurring single-nucleotide mutations in the SA1D2prox region, which ...

A new view of RNA: the 1989 discovery by Sidney Altman and Thomas Cech [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2020
The 1989 Nobel Prize Laureates in Chemistry Sidney Altman and Thomas Robert Cech made one of the most important discoveries in molecular genetics. Independently of each other, they demonstra­ted new experimental evidence that RNA molecules can not only ...

Minigene Splicing Assays Identify 12 Spliceogenic Variants of BRCA2 Exons 14 and 15

open access: yesFrontiers in Genetics, 2019
A relevant fraction of BRCA2 variants is associated with splicing alterations and with an increased risk of hereditary breast and ovarian cancer (HBOC). In this work, we have carried out a thorough study of variants from BRCA2 exons 14 and 15 reported at
