概述| 货号 | 10317-100ug |
| 描述 | There are seven human sirtuins, also known as class III HDACs, which have been designated SIRT1-SIRT7. Each is involved in various post-translational modifications by utilizing NAD dependent deacetylase and ADP-ribosyltransferase activities. SIRT4 is a mitochondrial ADP-ribosyltransferase responsible for the transfer of ADP-ribose from NAD to specific substrates such as glutamate dehydrogenase (GDH).1 In caloric-sufficient conditions, SIRT4 ADP-ribosylates GDH, repressing its activity and correspondingly decreasing insulin secretion.2 There is some uncertainty about the relevance of sirtuin ribosyl transferase activity due to its very slow rate, which is about 500 times lower than the corresponding deacetylation reaction (for those that have been characterized).3 SIRT4 is found in many tissues, but is specifically enriched in the kidney, heart, brain, and liver. 2 |
