Nuclear-cytoplasmic shuttling of class IIa histone deacetylases regulates somatic cell reprogramming.

ABSTRACT: Class IIa histone deacetylases (HDACs) are a subfamily of HDACs with important functions in development and adult tissue homeostasis. As opposed to other HDACs, they lack catalytic function and bind transcription factors to recruit transcriptional co-regulators, mostly co-repressors such as nuclear receptor co-repressor (NCoR)/silencing mediator of retinoid and thyroid hormone receptor (SMRT). Class IIa HDACs enhance mouse somatic cell reprogramming to induced pluripotent stem cells (iPSCs) by repressing the function of the pro-mesenchymal transcription factor myocyte enhancer factor 2 (MEF2), which is upregulated during this process. Here, we describe, using HDAC4 and 7 as examples, that class IIa HDACs exhibit nuclear-cytoplasmic trafficking in reprogramming, being mostly cytoplasmic in
