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 posttranslational modification. Protein modifications relay chemical signals to alter cell fate and gene expression. Certain signals lead to disease while others do not. My lab established a leadership role in the area of genetic code expansion to investigate the role of disease-linked protein modifications. My lab engineered new methods to produce proteins with programmed modifications and elucidated their role in signaling pathways linked to disease. Recent breakthroughs in my lab enable programmed protein modification in living human cells. We recently developed novel optogenetic tools to visualize mistranslation in live cells. Expanding beyond individual proteins, we are now leading efforts to reveal the ability of naturally occurring tRNA mutants to induce proteome-wide mistranslation in models of neurodegenerative disease.
