RNF2 (E3 ubiquitin-protein ligase RING2) is a ligase that mediates monoubiquitination of Lys-119 of histone H2A (H2AK119Ub). Therefore, it plays a central role in histone code and gene regulation. The ligase activity is enhanced by BMI1/PCGF4. H2AK119Ub gives a specific tag for epigeneti transcriptional repression and participates in X chromosome inactivation of female mammals. RNF2 may be involved in the initiation of both imprinted and random X inactivation. RNF2 is also an essential component of a Polycomb group (PcG) multiprotein PRC1-like complex. This complex class is required to maintain the transcriptionally repressive state of many genes including Hox genes throughout development. The PcG PRC1 complex acts via chromatin remodeling and modification of histones and rendering chromatin heritably changed in its expressibility.
