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 (S. cerevisiae) is Sir2. SIRT1 is an enzyme which deacetylates proteins that contribute to cellular regulation (reaction to stressors, longevity) [1].
