FIGURE 2.
Sibling RRM pairs in species-specific proteins are more conserved. (A) Human RBPs with multiple RRMs were divided into two classes: the proteins shared among four different species (H. sapiens, M. musculus, D. melanogaster, and C. elegans) and the proteins found only in human. The similarity scores between sibling RRMs were calculated for each class and represented as a box plot. The score distributions were compared by t-test with P value indicated. The same analyses were also carried out using RBPs from M. musculus (B), D. melanogaster (C), and C. elegans (D).
