The impact of mutations and post-translational modifications on biomolecular interactions

High-throughput sequencing (HTS) and proteomics approaches now mean that tens of thousands of positional variations within genes or proteins can be identified in a single experiment. The vast majority of such variations are still new and require advanced methods to identify those that are important for disease or biological mechanism. We develop methods and perform analyses to interrogate these data. This work builds on our 15 years experience in relating structures to the interactome and to date we have studied dozens of disease mutation and post-translational modification datasets. Our aim is, for each mutation/modification and for each gene/protein to assess the overall impact on biomolecular interactions with sub-aims to help identify biological switches, deleterious or oncogenic mutations and other insights arising from a more mechanistic understanding of such changes in proteins. We continue to develope our Mechismo server to help scientists interpret these large and complicated datasets.
