Figure 4

The distribution of the P scores for each RNA-binding protein. The x-axis represents the nucleotide positions and the y-axis represents the P score of ±20 bases around the sequential motif site. The position 0 denotes the start position of the sequential motif. Positive P scores for each structural context indicate that the positions tend to prefer the structural context. The black box represents the sequential motif site. The dotted lines show the corrected significance levels of the Bonferroni correction (α=0.05). The panels represent the distribution of P scores for (A) QKI, (B) Pum2, (C) Lin28A, (D) FXR2(WGGA), (E) FMR1_7(ACUK), (F) FXR2(ACUK), (G) Nova and (H) SRSF1. B, bulge loop; H, hairpin loop; I, internal loop; S, stem; U, unstructured.
