Professional Interests
Cell surface carbohydrates have been demonstrated to be involved in a variety of biological recognition phenomena including cellular recognition and adhesion, regulation of inflammation, control of cell growth and metastasis. Although the structures of many of these carbohydrates have been elucidated, relatively little is known about their molecular recognition properties other than their interactions with glycosylases and lectins. Lectins are carbohydrate-binding proteins that are widely found in nature including plants, animals and pathogenic organisms. Lectins and the cell surface glycans of glycoproteins and glycolipids play important roles in cellular homeostasis and innate and adaptive immunity. Our research includes characterizing the biophysical and biochemical properties of lectins and their interactions with multivalent cellular glycans. We are also investigating the self-binding properties of carbohydrate tumor antigens and have presented evidence for their involvement in oncogenesis. Techniques used to explore these interactions include isothermal titration microcalorimetry, x-ray crystallography, atomic force microscopy and optical tweezers.
