Family relationships



E3 ubiquitin-protein ligase RING1 (EC: is one three E3 ubiquitin-protein ligases that mediate monoubiquitination of 'Lys-119' of histone H2A, which is a specific tag for repression of epigenetic transcription and particularly for inactivation of chromosome X of female mammals [PMID: 16359901, PMID: 15525528]. RING1 is a component of the Polycomb group (PcG) multiprotein PRC1-like complex, the repressive BCOR complex [PMID: 16943429], and the the complex in G0 phase [PMID: 12004135]. RING1 has a RING-type zinc finger.
