SIRT7 Antibody
Appearance: Colorless liquid
Shelf Life: 12 months
Background: The sirtuins represent a distinct class of trichostatin A-insensitive lysyl-deacetylases (class III HDACs) and have been shown to catalyze a reaction that couples lysine deacetylation to the formation of nicotinamide and O-acetyl-ADP-ribose from NAD+ and the abstracted acetyl group. SIRT7 is a member of this family of proteins and is present in prokaryotes and eukaryotes. All SIR2-like proteins have a sirtuin core domain, which contains a series of sequence motifs conserved in organisms ranging from bacteria to humans. Bacterial, yeast, and mammalian sirtuins are able to metabolize NAD+ and several act as mono-ADP-ribosyltransferases. The enzymatic function of sirtuins is not yet completely understood but as mentioned above, recent reports of histone-activated SIR2-mediated NAD+ metabolism and NAD+-activated SIR2-mediated histone deacetylation smuggest a possible coupled reciprocal activation mechanism involving interactions of SIR2 with NAD+ and the N-epsilon-acetyl-lysine groups of acetylated histone.
NCBI and Uniprot Product Information
NCBI Description
This 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 IV of the sirtuin family. [provided by RefSeq, Jul 2008]
Uniprot Description
SIRT7: NAD-dependent protein deacetylase that specifically mediates deacetylation of histone H3 at 'Lys-18' (H3K18Ac). In contrast to other histone deacetylases, displays selectivity for a single histone mark, H3K18Ac, directly linked to control of gene expression. H3K18Ac is mainly present around the transcription start site of genes and has been linked to activation of nuclear hormone receptors. SIRT7 thereby acts as a transcription repressor. Moreover, H3K18 hypoacetylation has been reported as a marker of malignancy in various cancers and seems to maintain the transformed phenotype of cancer cells. These data suggest that SIRT7 may play a key role in oncogenic transformation by suppresses expression of tumor suppressor genes by locus-specific deacetylation of H3K18Ac at promoter regions. Also required to restore the transcription of ribosomal RNA (rRNA) at the exit from mitosis: promotes the association of RNA polymerase I with the rDNA promoter region and coding region. Stimulates transcription activity of the RNA polymerase I complex. May also deacetylate p53/TP53 and promotes cell survival, however such data need additional confirmation. Belongs to the sirtuin family. Class IV subfamily. 3 isoforms of the human protein are produced by alternative splicing.

Product Notes
The SIRT7 sirt7 (Catalog #AAA840244) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The SIRT7 Antibody reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's SIRT7 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB). Western blot: 1-3 ug/ml. However, the optimal conditions should be determined individually. Researchers should empirically determine the suitability of the SIRT7 sirt7 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "SIRT7, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
