Many diseases are linked to protein misfolding induced by mutations or other factors.
Peripheral myelin protein 22 (PMP22) has four transmembrane segments and is a critical
component of the myelin sheath surrounding the axons of the peripheral nervous system.
Mutations in PMP22 that result in misfolding lead to Charcot-Marie-Tooth Disease, the most
common inherited disorder of the peripheral nervous system. Studies of the structures,
folding, stability, and molecular interactions of both wild type and disease-associated
mutants of human PMP22 are being conducted in order to illuminate how mutations in this
protein trigger misfolding and disease. We are also pursuing early-stage drug discovery for compounds that have the potential to treat CMTD by modulating its folding and trafficking in the cell.
