A method and system for keeping a protein-protein interaction (PPI) network database (DB) up-to-date by synchronizing protein information present in the PPI network DB with protein information present in a public DB which is frequently updated and is provided to the public are provided. The method of synchronizing protein information of a protein-protein interaction (PPI) network database (DB) includes: (a) choosing a protein from a PPI network DB which stores a plurality of pieces of PPI information; (b) receiving up-to-date protein information corresponding to the chosen protein from a global protein DB which stores a plurality of pieces of up-to-date protein information that can be provided to the public, and keeping the local protein DB up-to-date by performing a global synchronization operation on a local protein DB such that protein information which corresponds to the chosen protein and is present in the local protein DB can be updated with the received up-to-date protein information, the local protein DB storing a plurality of pieces of protein information corresponding to the PPI network DB; and (c) receiving updated protein information obtained through the global synchronization operation from the local protein DB, and keeping the PPI network up-to-date by performing a local synchronization operation on the PPI network DB such that protein information which corresponds to the chosen protein and is present in the PPI network DB can be updated with the received updated protein information.
