Splicing of pre?mRNAs is a necessary step for expression of the majority of genes
in higher eukaryotes, and its regulation through alternative splice site
selection shapes their proteomes. Defects in multiple splicing factors result in
aberrant mitotic progression, although the molecular basis for this observation
has remained elusive. Recent papers in The EMBO Journal and EMBO Reports reveal
that expression of sororin, a critical regulator that stabilizes cohesin rings in
sister chromatids, is exquisitely sensitive to defects in the splicing machinery,
thus explaining the striking link between spliceosome function and chromosome
segregation.
