STAT1 signaling is not regulated by a phosphorylation-acetylation switch.

Abstract excerpt

The treatment of cells with histone deacetylase inhibitors (HDACi) was reported to reveal the acetylation of STAT1 at lysine 410 and lysine 413 (O. H. Krämer et al., Genes Dev. 20:473-485, 2006). STAT1 acetylation was proposed to regulate apoptosis by facilitating binding to NF-κB and to control immune responses by suppressing STAT1 tyrosine phosphorylation, suggesting that STAT1 acetylation is a central...
