Signal transducers and activators of transcription (STAT) belong to a family of latent
cytoplasmic factors that can be activated by tyrosine phosphorylation by the members of the
Jak tyrosine kinase family in response to a variety of cytokines and growth factors. Activated
STATs form dimers and translocate into nucleus to induce expression of critical genes
essential for normal cellular events. In the past several years, significant progress has been

Signal transducers and activators of transcription (STAT) belong to a family of latent cytoplasmic factors that can be activated by tyrosine phosphorylation by the members of the Jak tyrosine kinase family in response to a variety of cytokines and growth factors. Activated STATs form dimers and translocate into nucleus to induce expression of critical genes essential for normal cellular events. In the past several years, significant progress has been made in the characterization of STAT acetylation, which is dependent on the balance between histone deacetylases (HDACs) and histone acetyltransferases (HATs) such as CBP/p300. Acetylation of STAT1, STAT2, STAT3, STAT5b and STAT6 has been identified. This review will highlight acetylation on the modulation of STAT activation.
