SIRT1 is 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.
SIRT1 antibody can be used for detection of SIRT1 by ELISA at 1:62500. SIRT1 antibody can be used for detection of SIRT1 by western blot at 5 μg/mL, and HRP conjugated secondary antibody should be diluted 1:50,000 - 100,000.
