SIRT4 encodes a member of the sirtuin family of proteins which are homologs of the Sir2 gene in budding yeast.
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 fully 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 IV of the sirtuin family.
SIRT4 is a mitochondrial ADP-ribosyltransferase that inhibits mitochondrial glutamate dehydrogenase 1 activity, thereby downregulating insulin secretion in response to amino acids.
