Summaries for CBX2 Gene

Entrez Gene Summary for CBX2 Gene

  • This gene encodes a component of the polycomb multiprotein complex, which is required to maintain the transcriptionally repressive state of many genes throughout development via chromatin remodeling and modification of histones. Disruption of this gene in mice results in male-to-female gonadal sex reversal. Mutations in this gene are also associated with gonadal dysgenesis in humans. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.[provided by RefSeq, Mar 2010]

GeneCards Summary for CBX2 Gene

CBX2 (Chromobox Homolog 2) is a Protein Coding gene. Diseases associated with CBX2 include 46xy sex reversal 5 and swyer syndrome. Among its related pathways are Cellular Senescence and Cellular Senescence. GO annotations related to this gene include chromatin binding and methylated histone binding. An important paralog of this gene is CBX4.

UniProtKB/Swiss-Prot for CBX2 Gene

  • 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.
