Given experimental limitations to find all interactions in a proteome, computational prediction/modeling of protein interactions is a prerequisite to proceed on the way to complete interactions at the proteome level. interaction attraction model by linking PPI to the protein domain interactions. Pruthvi Raj Bejugam. Important note: The method was essentially developed to predict DNA binding ability from the three-dimensional structure of a protein. However, as we discuss below, the methods we introduce have distinct features that enable us to account for protein–ligand interactions in the binding site while still allowing large-scale, genome-wide predictions to be made in a relatively limited amount of time on a modern computer cluster.
