Research Backgrounds

Function:

NAD-dependent protein deacetylase. Activates or deactivates mitochondrial target proteins by deacetylating key lysine residues. Known targets include ACSS1, IDH, GDH, SOD2, PDHA1, LCAD, SDHA and the ATP synthase subunit ATP5PO. Contributes to the regulation of the cellular energy metabolism. Important for regulating tissue-specific ATP levels. In response to metabolic stress, deacetylates transcription factor FOXO3 and recruits FOXO3 and mitochondrial RNA polymerase POLRMT to mtDNA to promote mtDNA transcription. 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).

PTMs:

Processed by mitochondrial processing peptidase (MPP) to give a 28 kDa product. Such processing is probably essential for its enzymatic activity.

Subcellular Location:

Mitochondrion matrix.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Tissue Specificity:

Widely expressed.

Subunit Structure:

Upon metabolic stress, forms a complex composed of FOXO3, SIRT3 and mitochondrial RNA polymerase POLRMT; the complex is recruited to mtDNA in a SIRT3-dependent manner. Also forms a complex composed of FOXO3, SIRT3, TFAM and POLRMT. Interacts with NDUFA9, ACSS1, IDH2 and GDH. Interacts with PCCA.

Family&Domains:

Belongs to the sirtuin family. Class I subfamily.

Application: IHC    Species: human    Sample: non-tumorous, para-tumorous, and tumorous tissues

Figure 5.|SIRT3 expression in non-tumorous, para-tumorous, and tumorous tissues. Te immunohistochemistry results of liver tissues showed that SIRT3 was positive in all cases. However, the positive intensity and express location in diferent groups were diferences. As showed in this Figure, SIRT3 mainly appeared in the cytoplasm in tumor tissue, but they were at the same time appearing in the cytoplasm and nucleus of para-tumorous and non-tumorous tissues. Moreover, the positive intensity of tumor tissue much lower than para-tumorous or non-tumorous tissues. Te diferences of SIRT3 positive intensity between tumorous and para-tumorous or non-tumorous tissue were statistically signifcant. Te data are presented as means ± SD from three independent experiments. ***P < 0.001.
