RNA Helicase DDX5 Inhibits Reprogramming to Pluripotency by miRNA-Based Repression of RYBP and its PRC1-Dependent and -Independent Functions

Bhaskar Chanda Stem Cell RNA-binding proteins have poorly defined roles in somatic cell reprogramming. Li et al. show that the RNA-binding protein DDX5 erects an epigenetic barrier to reprogramming. DDX5 controls RYBP through microRNA-125b to suppress specific somatic genes through deposition of H2AK119ub1 while activating an OCT4-KDM2B pluripotent gene program.
