Abovich N and Rosbash M (1997) Cross-intron bridging interactions in the yeast commitment complex are conserved in mammals. Cell 89(3):403-12
Abstract: The commitment complex is the first defined step in the yeast (S. cerevisiae) splicing pathway. It contains U1 snRNP as well as Mud2p, which resembles human U2AF65. In a genetic screen, we identified the yeast gene MSL-5, which is a novel commitment complex component. Genetic and biochemical criteria indicate a direct interaction between Msl5p and both Mud2p and the U1 snRNP protein Prp40p. This defines a bridge between the two ends of the intron. Msl5p (renamed BBP for branchpoint bridging protein) has a mammalian ortholog, the splicing factor SF1. Our results show that SF1 interacts strongly with human U2AF65, and that SF1 is a bona fide E complex component. This implies that aspects of these novel cross-intron protein-protein interactions are conserved between yeast and mammals.
