Sirtuin 2 (SIRT2)

Sirtuin 2(silent mating type information regulation 2 homolog) 2 (S. cerevisiae), also known as SIRT2, is a human gene.This gene encodes a member of the sirtuin family of proteins, homologs to the yeast Sir2 protein. Members of the sirtuin family are characterized by a sirtuin core domain and grouped into four classes. The functions of human sirtuins have not yet been determined; however, yeast sirtuin proteins are known to regulate epigenetic gene silencing and suppress recombination of rDNA. Studies suggest that the human sirtuins may function as intracellular regulatory proteins with mono-ADP-ribosyltransferase activity. The protein encoded by this gene is included in class I of the sirtuin family. Two transcript variants result from alternative splicing of this gene.
