Deletion mapping of the regions in p68 interacting with p68 and p72. In each case deletion derivatives were tested for interaction with the respective full-length partners in the yeast two-hybrid system. The amino acids included in each of the deletions are indicated as are the conserved ‘DEAD box’ motifs. FL, full length. +++, strong interaction, 100% blue colonies in <30 min; ++, intermediate interaction, >50% blue colonies in <4 h; +/–, weak interaction, <50% blue colonies in 24 h; –, no interaction, no blue colonies.
