Sirtuin 6 NAD+-dependent protein deacetylase

Molecularly, Sirt6 neural deletion results in striking hyperacetylation of histone H3 lysine 9 (H3K9) and lysine 56 (H3K56), two chromatin marks implicated in the regulation of gene activity and chromatin structure, in various brain regions including those involved in neuroendocrine regulation.

In yeast, Sir2 family proteins (sirtuins) regulate gene silencing, recombination, DNA repair, and aging via histone deacetylation. Most of the seven mammalian sirtuins (Sirt1–Sirt7) have been implicated as NAD+-dependent protein deacetylases with targets ranging from transcriptional regulators to metabolic enzymes.
