Table 3 Summary of results from the three analyses for the bait-prey pairs

# of unique pairs

# of pairs in which both fragments have domains

   # of pairs in which a domain pair has been already known or predicted as interacting partner

   # of pairs in which both fragments have a single domain

   # of pairs satisfying one or both criteria for domain detection above

# of pairs in which one or both fragments have nearly identical tertiary structures

   # of pairs in which one or both fragments have pockets

# of pairs with identical GO terms in any of the three categories

   cellular component

   molecular function

   biological process

   # of pairs with statistically significant (P < 0.05) similarity scores for GO-term assignment in two out of the three GO categories
