Areas of specialty

  • Protein structure and function
  • Protein folding, misfolding and aggregation
  • AAA+ ATPases
  • Molecular chaperones

Nearly every process in a living cell is carried out by protein complexes with highly organized structure. Among sophisticated protein machines, the AAA+ superfamily of proteins has recently attracted attention of researchers. AAA stands for "ATPases associated with a variety of cellular activities", which implies that these proteins use energy from ATP and perform a variety of functions. Our laboratory performs basic research oriented towards understanding molecular mechanisms underlying the function of AAA+ proteins. We use a combination of biological, biochemical and biophysical experimental approaches to study interactions between proteins, protein localization inside living cells, and structural changes in proteins and protein complexes.
