The numbers shown are for all pairs of persistent genes found in MINT, both without (and with) self interactions included. The table also shows the average number of proteinprotein interactions after 10,000 permutations, and estimated pvalues for getting a number of interactions after permutation that is larger than the experimental one. The number of genes of each class in the full set, represented in MINT and found as interaction pairs in MINT is shown in the table header.
