Protein-protein interactions underpin almost all biological functions, with the majority of proteins making at least one interaction with another. If we are to understand how function arises in the cell, an important prerequisite is to understand how protein-protein interactions arise and evolve.
When we analyse sets of related proteins we find that they vary substantially in the sets of interactions that they make. In other words, the network of interactions “rewires” itself through evolutionary time. This rewiring can give rise to enormous complexity and emergent biological function. We propose to study this process of evolutionary rewiring using computational methods. This will involve the use of protein structure, knowledge of how proteins bind through specific interfaces, and evolutionary models. This approach differs from other techniques that attempt to define specificity and binding surfaces in that it is “function-led” (based on the interaction network and the functional annotation), rather than being “sequence-led” (based one the partitioning of the sequences using a phylogenetic tree).
The majority of the data used will be derived from the yeast Saccharomyces cerevisiae. Since Manchester is a centre for yeast research there is may be a possibility to test computational predictions in collaboration with experimental labs.
