Current Lab Research
Our lab uses various biophysical techniques including cryo-electron microscopy as tools to study the function of macromolecular assemblies. Of particular interest are the atomic details of protein folding as carried out by molecular chaperones like hsp27 or chaperonins like hsp60/10.
Charcot-Marie-Tooth disease (CMT) and Distal Hereditary Motor Neuropathy (dHMN) cause dysfunction in nerves of the peripheral nervous system. Our studies aim to facilitate development of strategies for disease intervention through new effective drug therapies by determining the structure of Hsp27 in complex with its client proteins.
The mtHsp60 D29G and V98I missense mutations have shown direct correlation to hereditary spastic paraplegia type 13 (SPG13) and mitochondrial Hsp60 chaperonopathy (MitCHAP-60). We study various mtHsp60 protein folding intermediates with a focus on the disease-causing point mutations, D29G and V98I, leading to possible treatments.
