domain profile pairs PSI-MI MI:0037 This approach uses a protein interaction network of a given organism to infer interaction in another organism using information about the interacting region. The regions or domains involved in interactions are clustered if they share sequence similarity and have common interacting partners. The resulting domain profiles are then used to screen the proteome of another organism and domain-domain interactions are inferred. Ultimately, an inferred protein interaction map is built in this second organism. experimental knowledge based sequence based prediction feature prediction
