Description
Description
Polycomb group RING finger (PGRF) complexes contain a PGRF subunit and mediate post-translational protein modification. The best chatacterised of these are epigenetic regulators, such as the Polycomb repressive complex 1 (PRC1). (Adapted from FBrf0220020, FBrf0228921 and FBrf0264828.)
