highly significantP < 0.01
We observed highly significant overlap (hypergeometric P < 0.01) between the protein and the corresponding RNA targets for three (B52, SYP, and CG6227) of the 20 RBPs (Supplemental Table 11) and note that there is a strong tendency among all RBPs to cobind proteins and their mRNAs (Fisher's method P < 10 −8 ).
