Sirtuin 2. 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.
Sirtuin. Sirtuins are a family of signaling proteins involved in metabolic regulation. [ 2][ 3] They are ancient in animal evolution and appear to possess a highly conserved structure throughout all kingdoms of life. [ 2] Chemically, sirtuins are a class of proteins that possess either mono- ADP-ribosyltransferase or deacylase activity ...
Sirtuin-activating compound. 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. [ 1]
Sirtuin 6. Sirtuin 6 ( SIRT6 or Sirt6) is a stress responsive protein deacetylase and mono-ADP ribosyltransferase enzyme encoded by the SIRT6 gene. [ 5][ 6][ 7] In laboratory research, SIRT6 appears to function in multiple molecular pathways related to aging, including DNA repair, telomere maintenance, glycolysis and inflammation. [ 5]

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.
Automated patch clamping is beginning [1] to replace manual patch clamping as a method to measure the electrical activity of individual cells. Different techniques are used to automate patch clamp recordings from cells in cell culture and in vivo. This work has been ongoing since the late 1990s by research labs and companies trying to reduce ...
Patch clamp. A bacterial spheroplast patched with a glass pipette. A patch clamp recording of current reveals transitions between two conductance states of a single ion channel: closed (at top) and open (at bottom). The patch clamp technique is a laboratory technique in electrophysiology used to study ionic currents in individual isolated ...
