Supplementary information

SIRT3 also known as Sirtuin 3 and mitochondrial sirtuin is a deacetylase with a mass of roughly 44 kDa. This protein is mostly found in the mitochondria where it regulates the acetylation state of various substrates. It plays an important role in maintaining mitochondrial homeostasis by modifying protein activity. SIRT3 is evolutionarily conserved and highly expressed in tissues with high energy demand like the heart liver and brown adipose tissue.

Biological function summary

SIRT3 modulates energy homeostasis by deacetylating and regulating enzymes involved in metabolism. It is a part of the mitochondrial sirtuin family contributing to fatty acid oxidation and the antioxidant defense system. By targeting key metabolic enzymes SIRT3 directly impacts the tricarboxylic acid (TCA) cycle and oxidative phosphorylation processes. These functions highlight its role in maintaining energy efficiency and reducing reactive oxidative species.

Pathways

SIRT3 participates in vital metabolic pathways such as the TCA cycle and the urea cycle. It interacts with other proteins like MnSOD and IDH2 to enhance mitochondrial function and overall cellular metabolism. This helps control the balance between energy production and consumption integrating signals from the AMPK and NAD+-dependent pathways to coordinate responses to changes in energy availability.

SIRT3 has implications in metabolic syndrome and cancer. Reduced SIRT3 activity is associated with increased susceptibility to metabolic disturbances like obesity and type 2 diabetes. Its deficiency affects the regulation of ROS and metabolic adaptation linking it to tumorigenesis and cancer progression. As it connects with proteins like HIF-1α in hypoxic conditions SIRT3 plays a role in cellular adaptation to stress influencing disease progression.

Target data

NAD-dependent protein deacetylase (PubMed : 12186850, PubMed : 12374852, PubMed : 16788062, PubMed : 18680753, PubMed : 18794531, PubMed : 19535340, PubMed : 23283301, PubMed : 24121500, PubMed : 24252090). Activates or deactivates mitochondrial target proteins by deacetylating key lysine residues (PubMed : 12186850, PubMed : 12374852, PubMed : 16788062, PubMed : 18680753, PubMed : 18794531, PubMed : 23283301, PubMed : 24121500, PubMed : 24252090, PubMed : 38146092). Known targets include ACSS1, IDH, GDH, SOD2, PDHA1, LCAD, SDHA, MRPL12 and the ATP synthase subunit ATP5PO (PubMed : 16788062, PubMed : 18680753, PubMed : 19535340, PubMed : 24121500, PubMed : 24252090, PubMed : 38146092). Contributes to the regulation of the cellular energy metabolism (PubMed : 24252090). Important for regulating tissue-specific ATP levels (PubMed : 18794531). In response to metabolic stress, deacetylates transcription factor FOXO3 and recruits FOXO3 and mitochondrial RNA polymerase POLRMT to mtDNA to promote mtDNA transcription (PubMed : 23283301). Acts as a regulator of ceramide metabolism by mediating deacetylation of ceramide synthases CERS1, CERS2 and CERS6, thereby increasing their activity and promoting mitochondrial ceramide accumulation (By similarity). Regulates hepatic lipogenesis (By similarity). Uses NAD(+) substrate imported by SLC25A47, triggering downstream activation of PRKAA1/AMPK-alpha signaling cascade that ultimately downregulates sterol regulatory element-binding protein (SREBP) transcriptional activities and ATP-consuming lipogenesis to restore cellular energy balance (By similarity). In addition to protein deacetylase activity, also acts as a protein-lysine deacylase by recognizing other acyl groups, such as benzoyl and lactoyl, leading to protein debenzoylation and delactylation, respectively (PubMed : 39524354, PubMed : 36896611, PubMed : 37720100). Catalyzes debenzoylation of PPIF and ACLY (PubMed : 37720100). Mediates delactylation of CCNE2 and 'Lys-16' of histone H4 (H4K16la) (PubMed : 36896611, PubMed : 37720100).
