Bowhead whales can live for more than 200 years, and researchers have discovered a protein that might be the reason.
A team of scientists found that the cold-induced RNA-binding protein enhances DNA repair, specifically fixing double-stranded DNA breaks.
This protein not only has potential implications for bowhead whales, but also for other species: it was shown to extend the lives of Drosophila flies and enhance repair in human cells.
The protein enhances repair of double-stranded DNA breaks, a particularly troublesome kind of damage.
