| 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 recombition of rD. 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. Altertive splicing results in multiple transcript variants. [provided by RefSeq Dec 2008] |
