UniProtKB description:  Polycomb group (PcG) protein (PubMed:1898775). PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development (PubMed:1898775, PubMed:11493925, PubMed:11583617). PcG proteins are not required to initiate repression, but to maintain it during later stages of development (PubMed:1898775). Component of the PcG multiprotein PRC1 complex, a complex that acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A 'Lys-118', rendering chromatin heritably changed in its expressibility (PubMed:11493925, PubMed:11583617). Promotes locus-specific chromatin compaction (PubMed:11493925, PubMed:11583617). Binds to (N(6)-methyladenosine) DNA and thereby might implement repression of specific loci (PubMed:30078725).
