SIRT1

A gene on chromosome 10q21.3 that encodes a widely expressed NAD-dependent protein deacetylase, which links transcriptional regulation to intracellular energetics and co-ordinates distinct cellular functions such as cell cycle, response to DNA damage, metabolism, apoptosis and autophagy. SIRT1 can modulate chromatin function by deacetylating histones and altering the methylation of histones and DNA, leading to transcriptional repression. It deacetylates a broad range of transcription factors and co-regulators, up- and downregulating target gene expression.
