G-patch domain Yeast Spp2, a G-patch protein and spliceosome component, interacts with the ATP-dependent DExH-box splicing factor Prp2. As this interaction involves the G-patch sequence in Spp2 and is required for the recruitment of Prp2 to the spliceosome before the first catalytic step of splicing, it is proposed that Spp2 might be an accessory factor that confers spliceosome specificity on Prp2. |
