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. Promotes histone H3 trimethylation at Lys-9 (H3K9me3). Binds to trimethylated lysine residues in histones, and possibly also other proteins. Regulator of cellular lifespan by maintaining the repression of CDKN2A, but not by inducing telomerase activity. Recombinant protein corresponding to aa1-251 from full length human CBX7, fused to 6xHis-Tag at N-terminal, expressed in Yeast.
