additional information
evolution
SIRT6 belongs to the mammalian homologues of Sir2 histone NAD+-dependent deacylase family
evolution
sirtuin 6 (SIRT6) is a member of the sirtuin family of nicotinamide adenine dinucleotide?dependent protein deacetylases
evolution
sirtuin6 is a member of the sirtuin family which function as NAD+-dependent deacetylases
evolution
sirtuins are an evolutionarily conserved family of proteins originally defined as the class III histone deacetylases (HDACs). The sirtuin family of proteins share a conserved central catalytic domain and the ability to couple the cleavage of NAD+ to the removal of an acyl group from the epsilon-amino group of lysines. Each family member (SIRT1-7) contains variable N-terminal and C-terminal domains and has diverse subcellular localization and function
evolution
sirtuins, silent mating-type information regulation 2 (SIRTs), are a family of nicotinamide adenine dinucleotide (NAD+)-dependent histone deacetylases with important roles in regulating energy metabolism and senescence. SIRT6 reduces the upregulation of genes involved in inflammation, vascular remodeling, oxidative stress, and angiogenesis, including interleukin 1-beta
evolution
there are seven evolutionarily conserved mammalian sirtuins (SIRT1-7) distributed to different compartments of the cell. They possess different deacylation activities to post-translationally modulate functions of their targets influencing major cellular pathways. SIRT6 is associated with chromatin and possesses histone deacetylase as well as mono-ADP-ribosylase activities, for both of which it needs NAD+ as a co-substrate

SIRT6 is associated with chromatin and possesses histone deacetylase as well as mono-ADP-ribosylase activities, for both of which it needs NAD+ as a co-substrate
malfunction
knock-down of SIRT6 does not sensitize bladder cancer cell lines to DNA damaging drugs
malfunction
SIRT6 deficiency causes major retinal transmission defects concomitant to changes in expression of glycolytic genes and glutamate receptors, as well as elevated levels of apoptosis in inner retina cells
malfunction
SIRT6 loss suppresses proliferation and epidermal hyperplasia in mouse skin. Skin-specific deletion of SIRT6 in the mouse inhibits skin tumorigenesis
malfunction
enzyme inactivation in cells leads to histone H3-Lys18 hyperacetylation and aberrant accumulation of pericentric transcripts
malfunction
enzyme knockout is associated with derepression of Oct4, Sox2 and Nanog, which in turn causes an upregulation of Tet enzymes and elevated production of 5-hydroxymethylcytosine
malfunction
inhibiting SIRT6 activity enhances anti-multiple myeloma activity of doxorubicin in vivo
malfunction
SIRT6 depletion in cardiac fibroblasts results in increased cell proliferation and extracellular matrix deposition as well as significantly higher expression of alpha-smooth muscle actin, the classical marker of myofibroblast differentiation, and increased formation of focal adhesions. Notably, SIRT6 depletion further exacerbates angiotensin IIinduced myofibroblast differentiation

enzyme SIRT6 evolved in eukaryotes to perform multiple critical roles in modulating gene expression, metabolism, DNA repair, and lifespan. In this context, SIRT6 plays key roles as a tumor suppressor and a critical modulator of metabolic homeostasis. SIRT6 accomplishes the transfer of radiolabel from [32P]NAD+ through an intramolecular mechanism, suggesting that SIRT6 may utilize ADP-ribosylation as a method to autoregulate its own activity. By modulating H3K9 acetylation, SIRT6 appears to act as a co-repressor of transcription factors, such as nuclear factor kappaB (NF-kappaB) and hypoxia-inducible factor-1alpha (HIF-1alpha). The removal of H3K9 acetylation by SIRT6 helps to regulate telomeric chromatin and gene expression. The role of SIRT6 as a protein deacetylase seems to expand beyond histone proteins. In fact, SIRT6 can directly remove acetyl groups from non-histone proteins. For instance, SIRT6 regulates hepatic glucose production by deacetylating the K549 residue of histone acetyltransferase (HAT) GCN5 and promoting its enzymatic activity. SIRT6 can also deacetylate pyruvate kinase M2 (PKM2) at K433 residue, driving its nuclear export and suppressing PKM2 oncogenic functions. In addition to its NAD+-dependent deacetylation and ADP-ribosylation activity, SIRT6 is also able to catalyze long-chain fatty deacylation, acting as a deacylase of tumor necrosis factor-alpha (TNF-alpha) and multiple secreted proteins. SIRT6 contains a large hydrophobic pocket that may favorably interact with long-chain fatty acyl groups, such as myristoyl. Interaction with these long-chain fatty acyl groups may serve as a regulatory step to modulate the histone deacetylase activity of SIRT6. Regulation of SIRT6 in mammalian cells, SIRT6 has functions in DNA repair, gene expression, telomeric maintenance, mitosis and meiosis, and protein networks, detailed overview

in gastrointestinal tumors, SIRT6 acts as a tumor suppressor, through different mechanisms, which include its ability to prevent the Warburg effect and genomic instability. In other types of tumors, including multiple myeloma and skin squamous cell carcinoma, high SIRT6 expression is associated with poor clinical outcome and may act pro-oncogenically. SIRT6 is involved in the regulation of a wide number of metabolic processes. SIRT6 deacetylase activity regulates the activity of NAD(P)(H) pools and nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting enzyme in the NAD+ salvage pathway from nicotinamide, in cancer cells. By controlling the biosynthesis of NAD+, NAMPT regulates the activity of NAD+-converting enzymes, such as CD38, poly-ADP-ribosepolymerases, and sirtuins (SIRTs). SIRT6 expression modulates the intracellular NADP(H) levels and G6PD activity. SIRT6 expression levels regulate NAD+ levels in different organs. SIRT6 regulates eNAMPT secretion. NAMPT is a direct substrate of SIRT6 deacetylation, with a mechanism that upregulates NAMPT enzymatic activity. SIRT6 affects intracellular NAMPT activity, boosts NAD(P)(H) levels, and protects against oxidative stress. In cancer, SIRT6 has been reported to play a context-dependent role.

M70R
further decrease in nicotinamide sensitivity compared to wild-type
D63H
naturally occuring mutation in SIRT6, the homozygous inactivating mutation of histone deacetylase SIRT6 results in severe congenital anomalies and perinatal lethality in four affected fetuses, it causes human perinatal lethality, missense mutation SIRT6 p.D63H in affected fetal amniocytes. SIRT6 D63H mutant mESCs fail to form EBs and retain pluripotent gene expression. The amino acid change at Asp63 to a histidine results in virtually complete loss of H3K9 deacetylase and demyristoylase functions. Asp63 is located in the NAD+-binding pocket, forming hydrogen bonds with neighboring amino acids and thus providing structure to the NAD+-binding loop

H131Y
the mutant enzyme can still bind NAD+ but has a decreased ability to bind ADP-ribose

D63H
naturally occuring mutation in SIRT6, the homozygous inactivating mutation of histone deacetylase SIRT6. Asp63 is located in the NAD+-binding pocket, forming hydrogen bonds with neighboring amino acids and thus providing structure to the NAD+-binding loop
H133Y
a catalytically inactive mutant of SIRT6, the acetylation level of PER2 is significantly increased in SIRT6-KO HEK293 cells compared to wild-type
additional information
G60A
the mutant is a lysine defatty acylase in vitro with substantially decreased deacetylase activity in vitro and no detectable deacetylase activity in cells
G60A
the SIRT6 G60A mutant retains an efficient defatty-acylase activity, but has significantly decreased deacetylase activity
H133Y
when human Sirt6 wild-type enzyme is overexpressed in Sirt6 KO MEF cells, tumor necrosis factor alpha has lower fatty acylation level than tumor necrosis factor alpha from cells without overexpression of human Sirt6, while overexpression of human Sirt6 H133Y catalytic mutant does not have much effect on tumor necrosis factor alpha fatty acylation
H133Y
catalytically inactive SIRT6 mutant, the SIRT6 H133Y mutant without histone deacetylase activity fails to inhibit phosphorylation and nuclear translocation of Smad2
R65A
the mutant shows only ADP-ribosyltransferase activity but no deacetylase activity
R65A
site-directed mutagenesis, the SIRT6 variant cannot be stimulated toward deacetylation by activator compounds. The R65A variant is similarly deficient in the ability to display enhanced catalysis with myristoylated substrates, suggesting that common catalytic steps are hampered

generation of SIRT6 knockout human mesenchymal stem cells (hMSCs) by targeted gene editing. For generation of SIRT6-deficient human embryonic stem cells (hESCs), the exon 1 of SIRT6 gene is removed in hESCs by a transcription activator-like effector nuclease. SIRT6-deficient hMSCs exhibit accelerated functional decay, a feature distinct from typical premature cellular senescence. Rather than compromised chromosomal stability, SIRT6-null hMSCs are predominately characterized by dysregulated redox metabolism and increased sensitivity to the oxidative stress. SIRT6 forms a protein complex with both nuclear factor erythroid 2-related factor 2 (NRF2) and RNA polymerase II, which is required for the transactivation of NRF2-regulated antioxidant genes, including heme oxygenase 1 (HO-1).
