Golgi stress induces SIRT2 to counteract Shigella infection via defatty-acylation

Abstract

Here the authors revealed a role for the protein deacetylase SIRT2 in Golgi stress, particularly induced by bacterial infection. Shigella secrete effector proteins such as IcsB, which transfers fatty acyl groups to modify host proteins to evade host immune surveillance. The upregulated SIRT2 counteracts this function by removing the fatty acyl groups and enhancing the killing of Shigella.
