Most of protein-coding human genes are subjected to alternative pre-mRNA splicing. Document Actions Export Bibliography. Abstract Alternative 3′-terminal exons, which use intronic polyadenylation sites, are generally less conserved and expressed at lower levels than the last exon of genes.

These findings provide new insights into the evolution, function andmolecular regulation of alternative 3′-terminal exons.
FAQ Frequently asked questions Display options. These splicing sequences make splicing susceptible to polymorphisms and mutations. HuR binding to the alternative 3′-terminal exon in the pre-messenger RNA promotes its splicing, and is reduced by topoisomerase inhibitors.
The generation of two or more different mature mRNA’s from the same primary transcript through variation in the sites of splicing.
Although many alterations are caused by mutations in splicing sequence i. Info A recently evolved class of alternative 3′-terminal exons involved in cell cycle regulation by topoisomerase inhibitors. Initial download of the metrics may take a while. Issue Med Sci Paris. Following growing of knowledge regarding splicing regulation, several approaches have been developed to compensate for the effect of deleterious mutations and to restore sufficient amounts of functional protein.

Med Sci Paris ; Services Articles citing this article CrossRef 2. A collection of writing tools that cover the many facets of English and French grammar, style and usage. Here we discover a class of human genes, in which the last exon appeared recently during evolution, and the major gene product uses an alternative 3′-terminal exon corresponding to the ancestral last exon of the gene.
Glossaries and vocabularies Access Translation Bureau glossaries and vocabularies. This novel class of alternative 3′-terminal exons are downregulated on a large scale by doxorubicin, a cytostatic drug targeting topoisomerase II, and play a role in cell cycle regulation, including centromere-kinetochore assembly.

This regulation is under epissxge of the spliceosome and several splicing factors are also required to modulate the alternative usage of splice sites.
Examples of associations between human rare diseases and defects in pre-messenger RNA splicing are accumulating.
