Function
Polycomb group (PcG) protein. 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. The mes-2/mes-3/mes-6 complex may participate in the global inactivation of the X chromosomes in germline cells. The complex may act via methylation of histone H3 'Lys-27', rendering chromatin heritably changed in its expressibility. This complex is required to exclude mes-4 from the inactivated X-chromosomes in germline cells (PubMed:12077420, PubMed:15380065). Required for small-RNA-induced H3K27 trimethylation (PubMed:26365259).
