Figure 3.
The preference of syn and C2' endo conformation in RRM-RNA interactions. Nucleotides in syn conformation or C2' endo conformation are presented as following: A are presented as red, U are presented as green, C are presented as blue and G are presented as yellow. Nucleotides in anti conformation or not in C2' endo conformation which are involved in the interactions are shown as gray. P value (Fisher's exact test) indicates the statistical preference of nucleotides in syn or C2' endo conformations to be involved in interactions between the RNA and the RRM domain, relative to the general abundance in all other protein-RNA interactions.
