Naïve pluripotency is characterized by distinctly open chromatin and repressed endogenous retroviruses. Here the authors show that MPP8 and its association with the core HUSH complex is essential for naïve pluripotent cells; also that repression of LINE1 elements by MPP8 does not require chromatin binding, nor H3K9me3.
