Abstract

A functional analysis of protein fold interaction suggested that structural fold familieshave gradually acquired more diverse interacting partners while maintaining central biochemical interactions and functions. This means thatthe protein interaction network (map) maintains its robust architecture due to the functional constraints associated with the interactions.
