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.

Link to PubMed entry. 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.

Data correspond to usage on the plateform after This regulation is under control of the spliceosome and several splicing factors are also required to modulate the alternative usage of splice sites.

Following growing of knowledge regarding splicing regulation, several approaches have been developed to compensate for the effect of deleterious mutations and eissage restore sufficient amounts of functional protein. Examples of associations between human rare diseases and defects in pre-messenger RNA splicing are accumulating.
