Statement of Research Interests
My research is focused on the understanding of the molecular mechanism regulating signaling in plants. Signaling usually involved multi-step signal transduction. A common way cells relay molecular messages is by reversible protein phosphorylation. Protein kinases add phosphates to their target protein(s) and protein phosphatases remove them.
We are using the model plant Arabidopsis thaliana and a combination of forward and reverse genetics and biochemistry to determine the function of genes involved in signaling. We are specifically interested in two different types of signaling molecules:
- receptor like kinases: these are transmembrane proteins with an extracellular part that can binds a ligand and an extracellular kinase domain and are used to transduce external messages into the cell.
- phosphobinding domains: these are domains that specially bind to phosphorylated peptides.
