  • Research Description
      Protein glycosylation is an essential modification that functions in many biological roles ranging from the stabilization of protein structure to the regulation of cell surface properties. The N-linked oligosaccharides attached to proteins are the most common, most complex and most functionally diverse covalent modification that exist. Our research aims to understand how this modification is regulated, how glycoproteins mediate their biological roles at the cell surface, and how cell wall biosynthesis is coordinated with growth and division. As a model system for these studies, we use the budding yeast S. cerevisiae so that we can apply a combined genetic, biochemical, and cell biological approach to address these problems. Since cell surface carbohydrates are among the most important virulence determinants of pathogenic fungi, a major effort is also underway to understand the regulation of cell surface glycoprotein synthesis in the human fungal pathogen,  Candida albicans .
