Engineering the Next Generation of Protein Therapeutics
A major long-term interest of our group is the engineering of proteins for pharmaceutical and biotechnology applications. To this end, we have developed a set of high throughput screening techniques relying on bacterial expression and flow cytometry that enable the isolation of novel proteins with desired functions from ensembles (“libraries”) of hundreds of millions of protein variants. These studies have led to the engineering of antibodies exhibiting ultra-high antigen affinity, serum and/or novel effector functions, and of therapeutic enzymes that exhibit exquisite catalytic activity and optimal pharmacological properties. Examples that will be discussed as part of this talk include:
(a) The isolation, expression and therapeutic optimization (Fc engineering) of IgG in E.coli
(b) “Humanized” non-immunogenic enzymes for amino acid depletion in cancer.
(c) Proteases that exhibit exceptional activity and selectivity towards the cleavage of desired peptide targets.
