An overview of RNA splicing and functioning of splicing factors in land plant chloroplasts
RNA splicing refers to a process by which introns of a pre-mRNA are excised and the exons at both ends are joined together. Chloroplast introns are inherently self-splicing ribozymes, but over time, they have lost self-splicing ability due to the ...

A splicing-dependent transcriptional checkpoint associated with prespliceosome formation
There is good evidence for functional interactions between splicing and transcription in eukaryotes, but how and why these processes are coupled remain unknown.

Characterization of factors involved in the coupling of 3' end processing and splicing and in the 3' end formation of mRNA precursors [PDF]
Eukaryotic mRNA precursors are processed at their 5’ and 3’ ends and are spliced prior to their export from the nucleus to the cytoplasm. Although all three processing reactions can be studied separately in vitro, they are coupled in vivo.

PPP3CB overexpression mediates EGFR TKI resistance in lung tumors via calcineurin/MEK/ERK signaling
A triple osimertinib/calcineurin A/trametinib combination of treatment overcomes acquired resistance to EGFR TKI in EGFR-mutant lung adenocarcinoma cells that overexpress PPP3CB.

A trio of unique alternative splicing patterns : the splicing of tandem NAGNAG acceptors, transcription-start-site-dependent and mutually dependent cassette exons [PDF]
With the rapid increase in the volume of genomic and transcript data in mouse and human, a diverse set of alternative splicing patterns can be discovered.

The U5 snRNA loop 1 aligns the 5' and 3' exons for ligation during the second step of pre-mRNA splicing. U5 is intimately associated with Prp8, which mediates pre-mRNA repositioning within the catalytic core of the spliceosome and interacts directly with

Domain orientation in the RNA helicase YxiN and the role of conformational changes for RNA unwinding [PDF]
The RNA helicase YxiN from Bacillus subtilis is a member of the family of DEAD box proteins. YxiN is able to unwind RNA double strands in an ATP-dependent manner. The ability to catalyse RNA rearrangement is in vivo presumably necessary for the bacterial

Functional characterization of Ysh1p, the yeast endonuclease involved in 3" end processing and in transcription termination of RNA polymerase II transcripts [PDF]
Eukaryotic RNA polymerase II (RNAP II) is involved in the synthesis of two major classes of transcripts: messenger RNAs (mRNAs) and small nuclear and small nucleolar RNAs.

Developments in RNA Splicing and Disease [PDF]
Pre-mRNA processing, including 5'-end capping, splicing, editing, and polyadenylation, consists of a series of orchestrated and primarily cotranscriptional steps that ensure both the high fidelity and extreme diversity characteristic of eukaryotic gene expression.
