Sir2-like Family Deacetylases
Silent information regulator (Sir2)-like family deacetylases (also known as sirtuins) are a group of enzymes closely related to histone deacetylases. These enzymes can be found in the cytoplasm, mitochondria or nucleus and are ubiquitously expressed. Sir2-like family deacetylases catalyze the removal of acetyl groups from lysine residues in histones and non-histone proteins, which is coupled to NAD+ hydrolysis.
In general, sirtuins do not act autonomously but as components of large multiprotein complexes, such as pRb-E2F and mSin3A, that mediate important transcription regulatory pathways.
Sirtuins have a role in regulation of transcription and apoptosis leading to substantial interest in inhibitors of these enzymes as possible antineoplastic agents. In addition, Sir2-like family deacetylases are involved in the normal ageing process through their role in resistance to cellular stress.View all products for Sir2-like Family Deacetylases »
