Figure 3From: Structure and dynamics of the post-transcriptional mRNA-processing machineryRibbon diagrams of the structures of the RNA-binding domains of TAP and PAP compared with the known structures of Sex lethal and ribosomal protein S6. The structures are shown in a similar orientation after optimal superposition. Note that, despite the similar folding, none of these proteins exhibits significant sequence similarities.
