Background
SIRT1 (Sirtuin 1, SIR2L1) is a member of the Sirtuin family of proteins related to the yeast Sir2 protein. Like Sir2 and other Sirtuins, SIRT1 is an NAD+-dependent histone and protein deacetylase. SIRT1 catalyzes the removal of acetyl groups from a variety of protein substrates (NBS1, p53, Ku70, etc.) as well as from Histone H4 Lys16 (H4K16). SIRT1 is involved in the regulation of a number of cellular processes, including transcription, metabolism, DNA repair and aging, and increased SIRT1 is associated with extended lifespan of C. elegans.
Application Notes
Recombinant SIRT1 protein is useful for histone deacetylase assays and the study of DNA Repair.

HTRF assay for SIRT1 (193-741) activity
3 µM histone peptide H3K9ac (1-21) was incubated with SIRT1 (193-741) in reaction buffer for 30 min at 37 °C. Anti-H3K9me0 antibody was used to detect reaction products.
