NAD-dependent histone deacetylase involved in heterochromatic silencing. Mildly suppresses the heterochromatin-mediated silencing phenomenon known as position-effect variegation (PEV). Required for epigenetic silencing of the polycomb group proteins. Has histone H4 deacetylase activity in vitro. Required maternally for establishing proper segmentation of the embryo. Involved in sex determination. May be involved in the regulation of life span.

Sir2 in the mushroom bodies promotes short-term ethanol-induced behavioral plasticity by allowing changes in the expression of presynaptic molecules.PMID:27170122
The role of Sirt1 in Notch signalling is, therefore, more complex than previously recognized, and its diverse effects may be explained by a plethora of Sirt1 substrates involved in the regulation of Notch signalling.PMID:27623778
A lowered gene dosage of Sir2, in mutant heterozygotes, can extend normal longevity and greatly augment survivorship during amino-acid starvation in Drosophila.PMID:27074822
Drosophila HNF4 mutants display diabetic phenotypes similar to those of sir2 mutants, and protein levels for dHNF4 are reduced in sir2 mutant animals. Sir2 exerts these effects by deacetylating and stabilizing dHNF4 through protein interactions.PMID:27058248
Low oxygen partial pressure of highly resistant Drosophila significantly reduces the time of restitution and increases the expression of Sir2 and CG14740 genes.PMID:25335240
Using two transgenic dSir2 lines that were reported not to extend life span, we show significant life span extension when dSir2 expression is induced between 2 and 5-fold.PMID:24036492
This study provides additional independent evidence for the concept of Sir2 as a longevity gene and as a promising pharmacological target to cure age-related diseases.PMID:23765091
dSir2 in the adult fat body, but not in muscles, regulates life span in a diet-dependent manner.PMID:23246004

negative findings do not rule out a role for sirtuins in determination of metazoan lifespan, but they do cast doubt on the robustness of the previously reported effects of sirtuins on lifespan in C. elegans and DrosophilaPMID:21938067
Evidence in Drosophila implicates Sir2 in at least some of the beneficial effects of caloric restrictionPMID:20728527
These findings point to a Sir2-mediated pathway that activates a catabolic response to amino-acid starvation irrespective of the sugar content of the diet.PMID:21085633
Dmp53 is a down stream target of dSir2 enzymatic activity and mediates some aspects of the life span extending effects of caloric restriction.PMID:19851477

Sir2 interacts with members of the Hairy/Deadpan/E(Spl) family of bHLH euchromatic repressors, key regulators of Drosophila development. Sir2 plays a role in both euchromatic repression and heterochromatic silencing.PMID:12086602
