| Biochem/physiol Actions: | Silent information regulator 2 (Sir2) acts as a nicotine adenine dinucleotide (NAD) dependent deacetylase and is implicated in various biological processes such as regulation of transcriptional repression, recombination, the cell-division cycle, microtubule organization, and cellular responses to DNA-damaging agents. In addition, sirtuins also regulate the process involved in aging. Sir2 plays a vital role in mammalian metabolic homeostasis and is considered to be a potent therapeutic target for the treatment of type 2 diabetes. Sir2 has a crucial role in reduction of microglial activation and brain inflammation. Therefore, loss of Sir2 activity increases the risk of susceptibility to neurodegenerative diseases. |
| General description: | Silent information regulator 2 (Sir2) or sirtuin 2 is encoded by the gene mapped to human chromosome 19q13.2. It belongs to class Ib of sirtuin protein family. Sir2 is characterized with a catalytic domain containing two different domains that bind NAD and the acetyl-lysine substrate, respectively. Apart from this, it also constitutes variable NH2 and COOH-terminal domains involved in the regulation of subcellular localizations and catalytic activity. sirtuin 2 is mainly expressed in cytosol but its migration between cytosol and nucleus facilitates the deacetylation of both α-tubulin and histones. Human Sirtuin 2, GenBank Accession No. NM_030593, amino acids 50-356 with C-terminal His tag, MW = 35.5kDa, expressed in Escherichia coli expression system. |
