SIRT4 Is a Regulator of Insulin Secretion

Cell Chem Biol. 2017 Jun 22;24(6):656-658. doi: 10.1016/j.chembiol.2017.06.002.

Abstract

In a recent issue of Cell Metabolism, Anderson et al. (2017) report that SIRT4 regulates insulin sensitivity in the pancreas via activation of methylcrotonyl-CoA carboxylase 1 (MCCC1) by removal of dicarboxyacyl-lysine modifications. Thus, SIRT4 activates leucine catabolism and causes decreased secretion of insulin from the pancreas.
