PcG PRC1 complex acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A 'Lys-119', rendering chromatin heritably changed in its expressibility. Within the PRC1-like complex, regulates RNF2 ubiquitin ligase activity (PubMed:26151332). Plays a redundant role with PCGF5 as part of a PRC1-like complex that mediates monoubiquitination of histone H2A 'Lys-119' on the X chromosome and is required for normal silencing of one copy of the X chromosome in XX females (By similarity). {ECO:0000250|UniProtKB:Q8BTQ0, ECO:0000269|PubMed:26151332}. |zf-C3HC4| |inactivation of X chromosome by genetic imprinting| |X chromosome| |histone H2A-K119 monoubiquitination| |PRC1 complex| |dosage compensation by inactivation of X chromosome| |regulation of gene expression by genetic imprinting| |histone H2A monoubiquitination| |dosage compensation| |histone H2A ubiquitination| |genetic imprinting| |PcG protein complex| |histone monoubiquitination| |histone ubiquitination| |protein monoubiquitination| |regulation of gene expression, epigenetic| |RNA polymerase II regulatory region sequence-specific DNA binding| |histone modification| |covalent chromatin modification| |DNA-binding transcription factor activity| |protein ubiquitination| |chromatin organization| |protein modification by small protein conjugation| |protein modification by small protein conjugation or removal| |chromosome organization| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp444|THZ531 0.225μM R08 exp444]]|-1.88| No correlation found to any other genes in chemogenomics.
