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