SIRT6 interacts with multiple chromatin-related proteins in a DNA-dependent manner. (A) SIRT6-Flag overexpressed in HEK 293T cells and co-immunoprecipitated (IP) with anti-Flag beads. Associated proteins were separated on SDS PAGE, silver stained and identified by mass spectrometry. HEK 293T cells overexpressing empty Flag plasmid were used as control. (B) Disruption of DNA-dependent interactions by EtBr. (C) In contrast to recombinant bacterial expressed SIRT1-Flag, recombinant bacterial expressed SIRT6-Flag did not co-immunoprecipitate with any of the histone octamers, H2A, H2B, H3 and H4, in vitro.
