Sirtuin 6 - Wikipedia
Sirtuin 6 (SIRT6 or Sirt6) is a stress responsive protein deacetylase and mono-ADP ribosyltransferase enzyme encoded by the SIRT6 gene. [5] [6] [7] In laboratory research, SIRT6 appears to function in multiple molecular pathways related to aging, including DNA repair, telomere maintenance, glycolysis and inflammation. [5]

This gene encodes a member of the sirtuin family of NAD-dependent enzymes that are implicated in cellular stress resistance, genomic stability, aging and energy homeostasis. The encoded protein is localized to the nucleus, exhibits ADP-ribosyl transferase and histone deacetylase activities, and plays a role in DNA repair, maintenance of ...
SIRT6 Widely Regulates Aging, Immunity, and Cancer
2022年4月5日 · During the transformation from early inflammation to late inflammation, SIRT6 deacetylates H3K9ac and H3K56ac on several glycolysis gene promoters, inhibits HIF-1α transcriptional activity, and reduces glycolysis activity to promote M2 polarization of macrophages .

Sirt6 is one such gene that not only regulates DNA repair, but also maintains epigenomic stability and promotes longevity. Specifically, SIRT6 promotes base excision repair (Mostoslavsky et al., 2006) and both the homologous recombination (HR) and the non-homologous end joining (NHEJ) pathways of DSB repair (Mao et al., 2011; Toiber et al., 2013).
Structure and Biochemical Functions of SIRT6 - ScienceDirect
2011年4月22日 · SIRT6 is a member of the evolutionarily conserved sirtuin family of NAD+-dependent protein deacetylases and functions in genomic stability and transcriptional control of glucose metabolism. Early reports suggested that SIRT6 performs ADP-ribosylation, whereas more recent studies have suggested that SIRT6 functions mainly as a histone deacetylase.
Sirtuin 6: linking longevity with genome and epigenome stability
2021年7月17日 · Sirtuin 6 (SIRT6) extends mammalian lifespan and promotes healthspan. SIRT6 maintains genomic stability through improved efficiency of DNA repair. SIRT6 maintains heterochromatin and silences repetitive genetic elements. Regulation of SIRT6 is a potential strategy for rejuvenation.

SIRT6, an enzyme highly expressed in skeletal muscles, brain, heart, liver, and thymus, affects transcriptional regulation in a tissue-specific manner. This enzyme has a two-domain structure that consists of a large Rossmann fold and a smaller and structurally more varied sequence containing a Zn (2+)-binding motif.
