Abstract


We have identified histone H4 as a high-expression suppressor of Sir2-induced inviability in yeast cells. Overexpression of histone H3 does not suppress Sir2-induced lethality, nor does overexpression of histone H4 alleles associated with silencing defects. These results suggest a direct and specific interaction between Sir2 and H4 in the silencing mechanism.
