CBX2 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. Involved in sexual development, acting as activator of NR5A1 expression. Defects in CBX2 are the cause of 46,XY sex reversal type 5 (SRXY5). It is a disorder of sex development. Affected individuals have a 46,XY karyotype but present as phenotypically normal females. 2 isoforms of the human protein are produced by alternative splicing.
