General description

Nicotinamide adenine dinucleotide (NAD)-dependent histone deacetylase (Sir2) is one of the silent information regulator genes in yeast. It belongs to a family of proteins, that is found in organisms ranging from bacteria to complex eukaryotes. Proteins of this family share a core domain showing 25-60% sequence identity. The mammalian Sir2 gene family is comprised of seven members which are designated as Sirt1-7.


synthetic peptide corresponding to amino acids 35-51 of human Sirt7, conjugated to KLH via a C-terminal cysteine residue. The sequence is identical in mouse.


Anti-Sirt7 antibody produced in rabbit has been used in western blotting analysis and immunofluorescence detection.

Physical form

Biochem/physiol Actions

Sirt7 (sirtuin 7) is extensively found in protein associated with active rRNA genes (rDNA), in the nucleolus. It interacts with RNA polymerase I (Pol I) and histones. Overexpression of Sirt7 increases Pol I-mediated transcription, whereas knockdown of Sirt7 or inhibition of its catalytic activity results in decreased association of Pol I with rDNA and reduces Pol I transcription. Depletion of Sirt7 stops cell proliferation and triggers apoptosis. High levels of Sirt7 expression are associated with breast cancer.
