Abstract

The sirtuin family protein SIRT6 is a stress-responsive NAD-dependent histone deacetylase with key roles in glucose homeostasis, DNA repair and cellular lifespan. SIRT6 is now shown to mediate deacetylation of histone H3 Lys18 specifically at pericentric chromatin, thus maintaining transcriptional silencing of satellite repeats in a manner independent of HP1 and trimethylated H3 Lys9, thereby assuring correct segregation of chromosomes.
