PcG protein complex

ID (Ontology)

GO:0031519 (Gene Ontology)

Definition

A chromatin-associated multiprotein complex containing Polycomb Group proteins. In Drosophila, Polycomb group proteins are involved in the long-term maintenance of gene repression, and PcG protein complexes associate with Polycomb group response elements (PREs) in target genes to regulate higher-order chromatin structure.[ PubMed:9372908 ]
