HIV- 1: To Splice Or Not To Splice, That Is THE Question [PDF]
HIV-1 transcribes only one kind of transcript – the full length genomic RNA. To make the mRNA transcripts for the accessory proteins Tat and Rev, the genomic RNA must completely splice. The mRNA transcripts for Vif, Vpr, and Env must splice but not completely.

Spliced leader trans-splicing [PDF]
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

The Signature of a Splice [PDF]
We study the behavior of the signature of colored links [Flo05, CF08] under the splice operation. We extend the construction to colored links in integral homology spheres and show that the signature is almost additive, with a correction term independent of the links. We interpret this correction term as the signature of a generalized Hopf link and give

To Splice or Not to Splice, That Is the Treatment [PDF]
In this issue of Cell Chemical Biology, Shibata et al. (2020) rescue expression of CFTR from a defective gene by inhibiting splicing factors required for the inclusion of a pathogenic pseudo exon. Their work highlights the untapped potential of RNA splicing as a therapeutic target.

Splice and Dice: Intronic microRNAs, Splicing and Cancer [PDF]
Introns span only a quarter of the human genome, yet they host around 60% of all known microRNAs. Emerging evidence indicates the adaptive advantage of microRNAs residing within introns is attributed to their complex co-regulation with transcription and alternative splicing of their host genes.

Maturation of mRNA termini occurs during transcription and can be aided by pausing of RNA polymerase II (RNAPII). In this issue of Molecular Cell, two groups now demonstrate that RNAPII pausing may also assist cotranscriptional splicing in S. cerevisiae.

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.

Newly synthesized small GTPases in the Ras and Rho families are prenylated by cytosolic prenyltransferases and then escorted by chaperones to membranes, the nucleus, and other sites where the GTPases participate in a variety of signaling cascades ...

Predominant contribution of cis-regulatory divergence in the evolution of mouse alternative splicing [PDF]
Divergence of alternative splicing represents one of the major driving forces to shape phenotypic diversity during evolution. However, the extent to which these divergences could be explained by the evolving cis-regulatory versus trans-acting factors ...

In all organisms, splicing occurs through the formation of spliceosome complexes, and splicing auxiliary factors are essential during splicing. U2AF65 is a crucial splicing cofactor, and the two typical RNA-recognition motifs at its center recognize and ...
