Prediction of Protein-Protein interactions using protein docking Working with Alfonso Valencia at the CNIO in Madrid we have demonstrated the ability to use a protein docking method to predict protein interaction partners (pairs of proteins that interact). Protein docking programs are generally used to predict the shape of the complex formed between pairs of proteins that are known to interact. This is a difficult problem and docking methods often fail to generate accurate models of complexes. It had therefore been widely thought that it was beyond the scope of such program to predict IF two proteins interact. For a set of known complexes we demonstrated that it is possible to distinguish the docking scores of the real complex from the individual proteins docked with a large set of decoy proteins. For more details see Wass et al., 2011, Mol Syst Biol 7:469.
Prediction of Ligand binding sites My work on predicting ligand binding sites started when we participated in CASP8. We made manual predictions of ligand binding sites by identifying homologous structures and superimposing them on models of the predicted structure of the target protein. This effectively superimposed the ligands of the homologues onto the model of the target protein from which we predicted the binding site of the target protein. More details are available on our CASP results page and our paper in the CASP8 Special Issue of Proteins - Wass, M.N. and Sternberg, M.J. (2009) Prediction of ligand binding sites using homologous structures and conservation at CASP8.Proteins, 77 Suppl 9:147-51. PubMed. We have continued to perform well in the recent CASP9 assessment. After CASP8 we automated our manual predictive approach in the 3DLigandSite server (http://www.sbg.bio.ic.ac.uk/3dligandsite).
