Protein Information
Name SIRT4 {ECO:0000255|HAMAP-Rule:MF_03161}
Synonyms SIR2L4
Function Acts both as NAD-dependent protein ADP-ribosyl transferase and NAD-dependent protein deacetylase. Catalyzes the transfer of ADP-ribosyl groups onto target proteins, including mitochondrial GLUD1, inhibiting GLUD1 enzyme activity. Acts as a negative regulator of mitochondrial glutamine metabolism by mediating mono ADP-ribosylation of GLUD1: expressed in response to DNA damage and negatively regulates anaplerosis by inhibiting GLUD1, leading to block metabolism of glutamine into tricarboxylic acid cycle and promoting cell cycle arrest. In response to mTORC1 signal, SIRT4 expression is repressed, promoting anaplerosis and cell proliferation. Acts as a tumor suppressor. Also acts as a NAD-dependent protein deacetylase: mediates deacetylation of 'Lys- 471' of MLYCD, inhibiting its activity, thereby acting as a regulator of lipid homeostasis. Down-regulates insulin secretion.
Cellular Location Mitochondrion matrix {ECO:0000255|HAMAP- Rule:MF_03161, ECO:0000269|PubMed:16079181, ECO:0000269|PubMed:16959573, ECO:0000269|PubMed:17715127}
Tissue Location Detected in vascular smooth muscle and striated muscle. Detected in insulin-producing beta-cells in pancreas islets of Langerhans (at protein level). Widely expressed. Weakly expressed in leukocytes and fetal thymus

This gene encodes a member of the sirtuin family ofproteins, homologs to the yeast Sir2 protein. Members of thesirtuin family are characterized by a sirtuin core domain andgrouped into four classes. The functions of human sirtuins have notyet been determined; however, yeast sirtuin proteins are known toregulate epigenetic gene silencing and suppress recombination ofrDNA. Studies suggest that the human sirtuins may function asintracellular regulatory proteins with mono-ADP-ribosyltransferaseactivity. The protein encoded by this gene is included in class IVof the sirtuin family.
