  • Understanding the evolution of protein interaction networks is crucial.

Purpose of the Study:

  • To analyze the evolution of protein fold interactions.
  • To investigate how protein interaction networks maintain robustness.

Main Methods:

  • Functional analysis of protein fold interactions.
  • Examination of structural fold families and their interaction partners.

Main Results:

  • Protein fold families have acquired increasingly diverse interacting partners over time.
  • Central biochemical interactions and functions are conserved.
  • The protein interaction network exhibits a robust architecture.

Conclusions:

  • Functional constraints on interactions drive the evolution of protein interaction networks.
  • The stability of the protein interaction network is maintained by conserved biochemical functions.
