WebOne technique, which has gained popularity recently, is the analysis of protein–protein interactions by the proximity ligation assay (PLA). Here, we describe a liver perfusion protocol and the detection of the histone deacetylase function of Sirtuin 6 (SIRT6) using PLA in pmHep. Based on techniques See more References WebDespite this, ample evidence suggests that Sirt6 functions in vivo as a transcriptional corepressor via deacetylation of H3K9ac near gene promoters . This discrepancy may be explained by the finding that Sirt6 deacetylase activity is enhanced by binding to free fatty acids ( 13 ), as well as association with nucleosomes ( 12 ).

WebSirt6 has several enzymatic activities, including NAD +-dependent deacetylase activity and mono-ADP-ribosyl transferase activity of acetyl groups and long-chain acyl groups. The … WebSIRT6 exhibits poor deacetylase activity in vitro, despite a clear increase of histone acetylation in SIRT6 deficient cells in vivo. To try to explain this difference, Cohen and colleagues looked at the difference in SIRT6 activity when it was in the presence of histones versus nucleosomes.

WebSIRT6 deacetylates H3K9ac and H3K56ac surrounding DSBs, in this way bridging γH2AX to chromatin remodeling. While the in vivo data demonstrated that SIRT6 K33Q deacetylation activity toward histone H3 was compromised, the in vitro deacetylation assay using a synthesized acetyl H3 peptide showed negligible effect.
