General description
Sirtuins are a family of closely related enzymes named after the yeast gene Sir2 (silent mating type information regulation 2). Members of the Sirtuin family have been found in nearly all organisms studied. Sirtuins are hypothesized to play a key role in an organism′s response to stresses (such as heat or starvation) and to be responsible for the lifespan-extending effects of calorie restriction. Sirtuins act by removing acetyl groups from proteins in the presence of NAD+; they are thus classified as "NAD+-dependent deacetylases". Sirtuins have been implicated in the regulation of aging, transcription, apoptosis and stress resistance. Sirt1 (also known as Sirtuin 1, Sir2L1, and Sir2a), the mammalian homolog of yeast Sir2, has been shown to deacetylate and thereby deactivate the p53 protein to regulate cellular processes.
Specificity
This antibody recognizes Sirt1.
