Liz Meiering’s research is focused on protein folding, dynamics, function, engineering and design.
Her research targets understanding neurodegenerative diseases like ALS, as well as engineering proteins to understand their fundamental characteristics. She also develops proteins for applications in biotechnology, including protein drugs.
- Proteins: folding, misfolding and aggregation, structure, dynamics, and function
- Protein engineering and design
- Protein thermodynamics and kinetics
- Biophysical chemistry and biochemistry
- Bionanotechnology and biomaterials
Professor Meiering’s research group is elucidating how the primary amino acid sequence of a protein determines its folding and function. Knowledge of the molecular mechanisms governing protein folding, dynamics and function is essential for understanding natural proteins, misfolding and toxicity of variant proteins in disease and biotechnology, and engineering or designing proteins for a great, and barely tapped, range of modern biotechnological and medical applications.
They use a multidisciplinary approach integrating complementary experimental and modelling methods, to produce, engineer, and analyze recombinant protein variants in bacteria (E. coli) using biochemical and biophysical techniques, such as: differential scanning and isothermal titration calorimetry (DSC, ITC), multi-dimensional heteronuclear NMR spectroscopy, optical spectroscopies (fluorescence, CD, FTIR), light scattering, stopped-flow rapid mixing, atomic force microscopy, and computational modelling (bioinformatics, Rosetta, molecular dynamics). They analyze diverse proteins of biological, biotechnological and medical importance.
Current projects include:
- Hisactophilin: folding and function of a model beta trefoil protein with regulated pH-dependent actin- and membrane-binding
- ThreeFoil: folding and function of a designed, symmetric, multivalent carbohydrate binding beta-trefoil protein
- Adnectins: stability and solubility of engineered target binding protein biologics
- Human Superoxide Dismutase: protein folding and aggregation toxicity in disease
