Target

  • 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 ATP5O. Contributes to the regulation of the cellular energy metabolism. Important for regulating tissue-specific ATP levels.
  • Tissue specificity

    Widely expressed.
  • Sequence similarities

    Belongs to the sirtuin family. Class I subfamily.
    Contains 1 deacetylase sirtuin-type domain.
  • Post-translational
    modifications

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

    Mitochondrion matrix.
  • Target information above from: UniProt accession Q9NTG7 The UniProt Consortium
    The Universal Protein Resource (UniProt) in 2010
    Nucleic Acids Res. 38:D142-D148 (2010) .
