NAD-dependent deacetylase sirtuin 2 is an enzyme that in humans is encoded by the SIRT2 gene. [ 5 ] [ 6 ] [ 7 ] SIRT2 is an NAD+ (nicotinamide adenine dinucleotide)-dependent deacetylase. Studies of this protein have often been divergent, highlighting the dependence of pleiotropic effects of SIRT2 on cellular context.
In yeast, roundworms, and fruitflies, sir2 is the name of one of the sirtuin-type proteins (see table below). [16] Mammals possess seven sirtuins (SIRT1–7) that occupy different subcellular compartments: SIRT1, SIRT6 and SIRT7 are predominantly in the nucleus, SIRT2 in the cytoplasm, and SIRT3, SIRT4 and SIRT5 in the mitochondria.

Sirtuin-activating compounds (STAC) are chemical compounds having an effect on sirtuins, a group of enzymes that use NAD+ to remove acetyl groups from proteins. They are caloric restriction mimetic compounds that may be helpful in treating various aging -related diseases.
Microplastics were detected in almost every seafood sample found off the coast of the western U.S. in a recent study. The particles were found in the edible tissue of six different species of fish.
According to a report from MyPerfectResume, 71% of American workers rely on a secondary source of income for various expenses, including paying off debt, saving for significant life milestones and...
Remains from all 67 victims of the midair collision over Washington, D.C., that sent an American Airlines regional plane and an Army Black Hawk helicopter crashing into the Potomac River have been ...
Sirtuin 1, also known as NAD-dependent deacetylase sirtuin-1, is a protein that in humans is encoded by the SIRT1 gene. [5] [6] [7]SIRT1 stands for sirtuin (silent mating type information regulation 2 homolog) 1 (S. cerevisiae), referring to the fact that its sirtuin homolog (biological equivalent across species) in yeast (Saccharomyces cerevisiae) is Sir2.
Class I, which includes HDAC1, -2, -3 and -8 are related to yeast RPD3 gene; Class IIA, which includes HDAC4, -5, -7 and -9; Class IIB -6, and -10 are related to yeast Hda1 gene; Class III, also known as the sirtuins are related to the Sir2 gene and include SIRT1-7; Class IV, which contains only HDAC11 has features of both Class I and II.
