Co-expression PCC scores distribution. Pearson Correlation Coefficient score (see methods) is calculated to measure the correlation of two genes expression level of protein pairs in PRIN. Our results show an aggregation in PCC score between 0.3 and 0.8. With cut off 0.5, we finally obtained 28.3% of co-expressed protein pairs in PRIN, which farly exceeds a random level of 2.3% (see Discussion).
