      DescriptionAnti-Sirt1 Antibody, clone 3H10.2
      Background InformationThe Sir2 protein in yeast is known to function in transcriptional silencing processes through the deacetylation of histones H3 and H4. The more recently described human homologue of Sir2, known as SIRT1, has been found to associate with the tumor suppressor protein p53. There are now five described human homologs of yeast Sir2, which are named SIRT1-5.
      SIRT1 binds and deacetylates p53 with specificity for its C-terminal Lys382 residue in response to the upregulation of promyelocytic leukemia protein (PML) nuclear bodies or oncogenic Ras. The deacetylation of p53 SIRT1 has been shown to negatively regulate p53-mediated transcription, preventing cellular senescence and apoptosis induced by DNA damage and stress. SIRT1 is a HDAC which is important in establishing repressive chromatin structures and plays a role in increasing lifespan.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a member of the sirtuin family of proteins, homologs to the yeast Sir2 protein. Members of the sirtuin family are characterized by a sirtuin core domain and grouped into four classes. The functions of human sirtuins have not yet been determined; however, yeast sirtuin proteins are known to regulate epigenetic gene silencing and suppress recombination of rDNA. Studies suggest that the human sirtuins may function as intracellular regulatory proteins with mono-ADP-ribosyltransferase activity. The protein encoded by this gene is included in class I of the sirtuin family.

      UniProt Number
      UniProt SummaryFUNCTION: SwissProt: Q96EB6 # NAD-dependent deacetylase, which regulates processes such as apoptosis and muscle differentiation by deacetylating key proteins. Deacetylates 'Lys-382' of p53/TP53 and impairs its ability to induce proapoptotic program and modulate cell senescence. Deacetylates TAF1B and thereby represses rDNA transcription by the RNA polymerase I. Involved in HES1- and HEY2- mediated transcriptional repression. Inhibits skeletal muscle differentiation by deacetylating PCAF and MYOD1. May serve as a sensor of the cytosolic ratio of NAD(+)/NADH, which is essential in skeletal muscle cell differentiation. Despite some ability to deacetylate histones in vitro, such activity is either weak or inexistent in vivo. In case of HIV-1 infection, interacts with and deacetylates the viral Tat protein.
      COFACTOR: Binds 1 zinc ion per subunit (By similarity).
      SIZE: 747 amino acids; 81681 Da
      SUBUNIT: Interacts with TAF1B. Found in a complex with PCAF and MYOD1 (By similarity). Interacts with MLLT7/FOXO4, HES1, HEY2, p53/TP53 and PML.
      SUBCELLULAR LOCATION: Nucleus. Note=Recruited to the nuclear bodies via its interaction with PML.TISSUE SPECIFICITY: Widely expressed.
      SIMILARITY: SwissProt: Q96EB6 ## Belongs to the sirtuin family. & Contains 1 deacetylase sirtuin-type domain.
      MISCELLANEOUS: Red wine, which contains resveratrol, may participate in activation of sirtuin proteins, and may therefore participate in an extended lifespan as it has been observed in yeast.
