SIR2
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. Alternative splicing results in multiple transcript variants.

Forensic Context
A study in humans demonstrated that SIRT1 expression was significantly down-regulated in the subcutaneous adipose tissue of heavier co-twins from BMI-discordant monozygotic twin pairs [Jukarainen et al. DOI:10.1210/jc.2015-3095].
