Sirtuins (SIRT) are highly conserved NAD-dependent deacetylases that deacetylate histone/non-histone proteins which regulates numerous cellular processes including aging, DNA repair, cell cycle, metabolism, and survival under stress conditions. NAD-dependent protein deacetylase sirtuin-7 (SIRT7 or SIR2L7) is one of the SIRTs whose function is least understood and it may be found at peri-nuclear region of cytoplasm; associated with chromatin, rDNA promoter, transcribed regionas or nucleolar organizer regions during mitosis. SIRT7's lacks the conserved amino acids within catalytic domain associated with deacetylase actions, however, with its weak deacetylase activity, it can deacetylate tumor suppressor p53 leading to enhanced cell survival. SIRT7 complexes with ELK4 to deacetylate H3K18 at the promoters of NME1, COPS2 genes and deacetylate histone H3K18 acetylation at promoters of RPS7, RPS14, RPS20, which function as tumor suppressor genes in hematopoietic malignancy. SIRT7 connects chromatin remodeling complexes with the RNA Pol I machinery required for rDNA driving ribosome biogenesis in dividing cells. It is overexpressed in human thyroid carcinoma cell lines and tissues, but not in adenomas.
