Polycomb group RING finger protein 6 (Pcgf6)

Transcriptional repressor. May modulate the amount of histone H3K4Me3 by activating KDM5D histone demethylase.

Component of a Polycomb group (PcG) multiprotein PRC1-like complex, a complex class required to maintain the transcriptionally repressive state of many genes, including Hox genes, throughout development. PcG PRC1 complex acts via chromatin remodeling and modification of histones; it mediates monoubiquitination of histone H2A'Lys-119', rendering chromatin heritably changed in its expressibility.
