Protein Phosphatases in Cell Signalling

Our primary goal is to define the role of protein phosphatases in cellular events in response to both intra- and extra-cellularly derived signals. Protein phosphorylation is a common means to control protein function and regulates essentially every aspect of cell biology. We use a combination of biochemistry, molecular cell biology, bioinformatics and proteomics to investigate both human and plant phosphatase function. Current projects include cell cycle control by type one protein phosphatases, novel plant PPP-type phosphatases, protein phosphatase evolution, plant starch phosphatases and proteomics of PP1-complexes.
