Abstract: The unveiling of rules that govern drug-protein interactions is of paramount importance in drug discovery. To discover such relationships, we propose to use a novel method called DPA. Given a set of drug-protein interactions, DPA performs its tasks in several steps: (i) for each drug involved, its substructures are each converted into its fingerprints; (ii) for each protein involved, its protein domains are each converted into its fingerprints; (iii) a dependency measure between each drug substructure and protein domain is then computed based on the known interactions between the drugs and proteins, (iv) the dependency measures are then used to predict previously unknown drug-protein interactions. DPA has the advantage that it is able to perform its tasks effectively without requiring any 3D information about drug and protein structures. It makes use of molecular fingerprints which are information-rich and fast to compute. DPA has been tested with known drug-protein interaction data including enzymes, ion channels, protein-coupled receptors. Experimental results show that it can be very useful for predicting new drug-protein interaction as well as protein-ligand interactions. It can also be used to tackle problems such as ligand specificity thereby facilitating the drug discovery process.
