Professional memberships

Tissue engineering and repair expertise

Structure, folding and assembly of multidomain proteins, specifically those of the extracellular matrix (collagens, laminins, nidogens, tenascins, matrilins); alpha-helical coiled coils; protein sequence/structure relationship.

Circular Dichroism (CD) spectroscopy: An AVIV CD215 with a thermostated cell holder is available. CD spectroscopy can be useful to

a) estimate the secondary structure of proteins
b) determine whether mutations affect the structure, stability or binding interactions
c) determine the thermodynamics of folding of proteins, peptides and DNA
d) determine the kinetics of folding or drug binding.

The ability of a polypeptide to fold into its unique, functional tertiary structure depends on its amino acid sequence as well as its environment. Many disease-causing mutations and modifications exert their effects by interference with the proper folding process. The involvement of collagen in connective tissue diseases makes it important to elucidate the structural properties of the triple-helix. The influence of the chemical environment on protein folding and stability in general, and especially for fibrous proteins, has only recently attracted some attention. Thus in vivo biosynthesis occurs in a very crowded surroundings, and molecular chaperones help to ensure proper folding and prevent aggregation. Some small organic molecules (amino acids and derivatives, carbohydrates, methylamines) seem also to act as effective chemical chaperones. My work wants to further the understanding of the chain association, folding, and interaction of collagenous and -helical coiled coil protein domains, and to investigate the influence of chemical chaperones.
