Product Specific Information
Antibody detects endogenous levels of total CBX4.
Target Information
Polycomb group (PcG) proteins are chromatin-associated proteins important for embryonic and adult stem cell self-renewal and maintenance. Two distinct human PcG complexes have been identified.
Polycomb repressive complex I (PRC1) contains CBX4/Pc2, HPH1, and RING domain-containing proteins (RING1, RING2, BMI1).
CBX4 (Chromobox protein homolog 4 or PC2) functions as a transcriptional suppressor and acts as an E3 SUMO-protein ligase facilitating SUMO1 conjugation.
Depletion of CBX4 reduces cellular resistance to ionizing radiation and is directly involved in the cellular response to DNA damage.
