For cells to function properly, they must produce the right amount of each protein. It is a delicate balance: Both too little and too much can compromise essential cellular functions. A team from the University of Geneva (UNIGE) has now shown that even a modest excess of tubulin—the protein that a ssembles into microtubules, the cell's internal scaffolding—is enough to disrupt tissue architecture and reduce cell viability. Published in Nature Communications, the study demonstrates that the quantity of a protein is just as important as its function. ...read more read less
