Furthermore, we found a highly significant overlap of both mRBPomes orthologous pairs of proteins, suggesting high conservation of mRBPomes ( Fig. 3b ).

The sentences
Less frequent domains, such as the S1 domain (4 of 7 the annotated proteins) and the La domain (all 3 annotated proteins), were also enriched in the mRBPome but did not reach statistical significance by the chosen statistical test (complete domain analysis is given in Supplementary Table 2d ).
