Over- and under-represented GO terms of genes present at least once in a primate-specific PPI.

aObserved instances of the GO term. 1675 genes present in primate PPIs vs 7201 genes never observed in primate PPIs.bExpected number of occurrences among an randomly-selected set of genes of the same size.cP-values for the test of the hypothesis of no difference between the observed and expected number of occurrences of the term after a Bonferonni multiple-test correction.dTerm was under-represented among the primate-specific PPIs.
