Polycomb group (PcG) protein. Catalytic subunit of some PcG multiprotein complex, which methylates quot;Lys-27quot; of histone H3, leading to transcriptional repression of the affected target genes (PubMed:17881378). Required to regulate floral development by repressing the AGAMOUS homeotic gene in leaves, inflorescence stems and flowers (PubMed:17881378). Together with ATX1, modulates AG nucleosome methylation statement (PubMed:17881378). Regulates the antero-posterior organization of the endosperm, as well as the division and elongation rates of leaf cells. PcG proteins act by forming multiprotein complexes, which are required to maintain the transcriptionally repressive state of homeotic genes throughout development. PcG proteins are not required to initiate repression, but to maintain it during later stages of development.
