Our research is focused upon the interplay between the actin cytoskeleton and the molecular chaperone CCT. Actin is a highly abundant protein that is completely dependent upon CCT for its correct folding, thus placing CCT in a central role for protein quality control.
Using cultured mammalian cells as a model system, we use a combination of biochemistry and cell biology based techniques to address how the role of CCT extends beyond folding newly synthesized actin monomers to include modulating assembled actin structures. This is essential for our full understanding of all cellular events that depend of the actin system such as cell migration.
