The splicing factor U2AF small subunit is functionally conserved between fission yeast and humans.


The small subunit of U2AF, which functions in 3' splice site recognition, is more highly conserved than its heterodimeric partner yet is less thoroughly investigated. Remarkably, we find that the small subunit of Schizosaccharomyces pombe U2AF (U2AF(SM)) can be replaced in vivo by its human counterpart, demonstrating that the conservation extends to… (More)
