Research

The O’Donoghue lab investigates how proteome diversity, generated by either protein modification or mistranslation, impacts pathways to cancer and neurodegeneration.

Proteins involved in major human diseases undergo significant post-translational modification. Protein modifications relay chemical signals to alter cell fate and gene expression. My lab established a leadership role in the area of genetic code expansion to investigate the role of disease-linked protein modifications. The lab engineers new methods to produce proteins with programmed modifications and elucidates their role in signaling pathways linked to disease. Recent breakthroughs in the lab enable programmed protein modification in human cells.

We recently developed novel fluorescent reporters to visualize errors in proteins synthesis or mistranslation in live cells. The lab is now leading efforts to reveal the ability of naturally occurring transfer RNA (tRNA) mutants to induce proteome-wide mistranslation in models of neurodegenerative disease.
