Background InformationSir2 is short for Silent mating type Information Regulation-2. Sir2 (whose homolog in mammals is known as SIRT1, SIR2L1 or Sir2α) is the namesake of a family of closely related enzymes, the sirtuins. Members of this family have been found in nearly all organisms studied. Sirtuins are hypothesized to play a key role in an organism's response to stresses (such as heat or starvation) and to be responsible for the lifespan-extending effects of calorie restriction. Sirtuins act by removing acetyl groups from proteins in the presence of NAD+; they are thus classified as "NAD+-dependent deacetylases". In mammals, SIRT1 (the mammalian homolog of Sir2) has been shown to deacetylate and thereby deactivate the p53 protein.

Antibody TypeMonoclonal Antibody
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. Alternative splicing results in multiple transcript variants. [provided by RefSeq].

UniProt Number
UniProt SummaryFUNCTION: 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: 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.
