RNA Splicing by the Spliceosome
Annual Review of Biochemistry, 2020The spliceosome removes introns from messenger RNA precursors (pre-mRNA). Decades of biochemistry and genetics combined with recent structural studies of the spliceosome have produced a detailed view of the mechanism of splicing. In this review, we aim to make this mechanism understandable and provide several videos of the spliceosome in action to ...

Trends in Cancer, 2020
RNA splicing is an essential process that governs many aspects of cellular proliferation, survival, and differentiation. Considering the importance of RNA splicing in gene regulation, alterations in this pathway have been implicated in many human cancers.

Circular RNAs (circRNAs) are covalently closed single-stranded RNA molecules derived from exons by alternative mRNA splicing. Circularization of single-stranded RNA molecules was already described in 1976 for viroids in plants. Since then several additional types of circular RNAs in many species have been described such as the circular single-stranded ...

The splicing of long transcripts of RNA (copied from DNA in the cell nucleus) into smaller, specific mRNA (ready for export to the protein-producing machinery in the cytoplasm) is an important event in the regulation of gene expression in eukaryotic cells. The splicing reaction occurs as a late step in the nuclear pathway for synthesis of mRNAs.

RNA trans-splicing joins two or more RNA molecules into one RNA molecule. This process is a variation of the more familiar and common intron removal during nuclear pre-mRNA splicing. Both splicing reactions are a series of cleavage and ligation reactions resulting in the precise excision of introns and in the joining of exons to generate mature RNA. In

RNA Splicing in the Chloroplast
2006The chloroplast genomes of Chlamydomonas spp. contain introns that belong to the two major classes found in organelles: group I and group II. Some of the members of both classes are ribozymes capable of self-splicing in vitro and, indeed, most of the group I introns studied in Chlamydomonas spp. are autocatalyic.

Alternative splicing is a key element of eukaryotic gene expression. Almost all polymerase II transcripts are alternatively spliced. RNA is chemically and structurally more flexible than DNA, and can act as a catalyst. RNA is an active player in mediating genetic information, not just a static messenger.

RNA splicing in lower eukaryotes
Current Biology, 1992Recently, cis-acting elements and trans-acting RNA and protein factors necessary for splicing nuclear pre-mRNAs, group II introns or group III introns, have been discovered, and new roles for the splicing factors have been elucidated. Parallels among the pathways for splicing these different classes of introns have been identified.

Spliced leader RNA trans-splicing in metazoa
Parasitology Today, 1996Spliced leader trans-splicing is a form of RNA processing originally described and studied in parasitic kinetoplastida. This mechanism of gene expression also occurs in parasitic and free-living metazoa. In this review, Dick Davis describes current knowledge of the distribution, substrates, specificity and functional significance of trans-splicing in ...
