背景信息

CBX8. also known as Polycomb chromobox homolog 8. is a member of the Polycomb group (PcG) proteins that play critical roles in epigenetic regulation of gene expression. As a core component of the Polycomb Repressive Complex 1 (PRC1), CBX8 contributes to transcriptional repression by recognizing histone H3 lysine 27 trimethylation (H3K27me3), a chromatin mark deposited by PRC2. This interaction facilitates PRC1 recruitment to target genes, promoting chromatin compaction and gene silencing. CBX8 is part of the chromobox protein family, characterized by a conserved chromodomain that mediates binding to methylated histones. Unlike other CBX family members (e.g., CBX7), CBX8 exhibits context-dependent functions, influencing cell differentiation, stem cell maintenance, and cancer progression. Studies highlight its dual roles in oncogenesis, acting as either an oncogene or tumor suppressor depending on cellular context. For instance, CBX8 overexpression is linked to poor prognosis in certain cancers, while its loss may drive malignancy in others. CBX8-specific antibodies are essential tools for investigating its localization, protein interactions, and regulatory mechanisms in diseases. These antibodies are widely used in techniques like Western blotting, immunofluorescence, and chromatin immunoprecipitation (ChIP), aiding research into PRC1 dynamics and therapeutic targeting of epigenetic pathways.
