Research Interests

1. Development of a new sensitive quantitative approach (SRM) for protein footprinting in order to improve detection and quantitation of oxidized products that are present in less then 1% of the unmodified peptide and remained undetected in the current analysis. Hydroxyl radical-mediated protein footprinting in combination with mass spectrometry has recently been developed to define protein structure, protein folding, and protein-protein and protein-DNA interactions in solution. This method is based on the measurement of the reactivity of amino acid side-chain groups with hydroxyl radicals resulting in covalent modification (oxidation) of these residues according to their solvent accessibility. Digested protein then analyzed by mass spectrometry for the sites of oxidation.

2. Developing and implementing new mass spectrometry based approaches for examining the post-translational modifications of proteins. Post-translational modifications (PTMs) are covalent modification of the proteins after its translation. PTMs have been shown to be important features for regulating protein functions, determining their activity state, cellular location and dynamic interaction with other proteins. Because they are present in substoichiometric amounts on protein molecules, the comprehensive analysis has some analytical limitations.
