SIRT4 also known as Sirtuin 4 is a mitochondrial protein with a mass of approximately 36 kDa. It belongs to the sirtuin family of NAD+-dependent deacetylases. Unlike many other sirtuins SIRT4 does not function as a deacetylase; instead it exhibits ADP-ribosyltransferase activity. This activity regulates a range of mitochondrial functions. SIRT4 is expressed in various tissues including the liver pancreas and muscles where it plays different roles based on the tissue type.
Biological function summary
SIRT4 regulates energy metabolism and cellular stress responses. It plays key roles in the regulation of mitochondrial functions during fasting and impacts gluconeogenesis and fatty acid oxidation. SIRT4 inhibits glutamate dehydrogenase (GDH) affecting amino acid metabolism and insulin secretion. By acting in this capacity SIRT4 controls the flow of nutrients and energy homeostasis exhibiting its critical role in metabolic regulation.
Pathways
SIRT4 integrates into a broader metabolic network including the insulin signaling and AMPK pathways. It interacts with proteins like GDH and AMPK influencing mitochondrial energy output and stress response. This relationship places SIRT4 in an important position for maintaining energy balance and responding to cellular metabolic demands.
SIRT4 links to metabolic conditions such as diabetes and metabolic syndrome. Dysregulation of SIRT4 activity can lead to impaired insulin secretion and glucose intolerance. Furthermore SIRT4's interaction with other sirtuins particularly SIRT1 suggests a functional interplay in protecting against metabolic stress and possibly influencing the development of these metabolic disorders.
