Not a Chip off the Old Block

Study identifies unexpected function for mammalian version of yeast longevity protein

Mitch Leslie

Abstract: Like a headstrong teen who refuses to enter the family accounting business and joins a rock band instead, the mammalian protein SIRT1 breaks with its relatives, according to a new study. SIRT1's kin in yeast promotes cell division, but the protein prods mouse cells to abandon reproduction. The work reveals SIRT1's previously unknown role in handling long-lasting stress.
