产品详情

  • 产品描述：
    CSB-RA632623A0HU重组单克隆抗体是针对表观遗传调控核心因子CBX2开发的高特异性科研工具。该抗体靶向Polycomb抑制复合物（PRC1）的关键成员CBX2蛋白，该蛋白通过介导组蛋白H3K27me3修饰参与基因沉默、干细胞维持及细胞命运决定等重要生物学过程，其功能异常与胚胎发育异常及肿瘤发生密切相关。经严格验证，本抗体在Western Blot实验中可清晰识别内源性CBX2蛋白表达，推荐使用浓度为1:500至1:2000；同时具备ELISA检测应用兼容性，为研究者提供多重实验选择。该产品适用于探索多能性维持、细胞重编程、肿瘤表观遗传失调等研究领域，尤其适用于染色质动态调控机制解析、基因沉默模型构建及靶向PRC1复合物的功能研究。通过高批间一致性和低交叉反应性的优势，该抗体可为表观遗传学、发育生物学和肿瘤微环境研究提供可靠支持，所有应用均严格限定于基础科研范畴。

  • 功能：
    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. Binds to histone H3 trimethylated at 'Lys-9' (H3K9me3) or at 'Lys-27' (H3K27me3). Plays a role in the lineage differentiation of the germ layers in embryonic development. Involved in sexual development, acting as activator of NR5A1 expression.

    1. study indicates a distinct function of the shorter form of CBX2 and by identifying several of its unique targets, can advance our understanding of DSD pathogenesis and ultimately DSD diagnosis and management. PMID: 29998616
    2. These results suggest that CBX2's phosphorylation is critical for its transcriptional repression of target genes. PMID: 28992316
    3. Data show that basal-like subgroup was enriched for aggressive tumors and somatic mutations in trithorax-group genes and it overexpressed polycomb genes EZH2 and CBX2. PMID: 26431491
    4. up-regulated in metastatic castration-resistant prostate cancer and elevated expression correlates with poor clinical outcome PMID: 26877821
    5. CBX2 role in the sex development cascade is to stimulate the male pathway and concurrently inhibit the female pathway. PMID: 25569159
    6. CBX2 upregulation and amplification significantly correlated with metastatic progression and lower overall survival in many cancer types, particularly those of the breast PMID: 25225902
    7. This study does not support CBX2 gene disruption as a common cause of gonadal gonadal disorders of sex development. PMID: 23219007
    8. Two distinct mechanisms are involved in CBX2-mediated gene silencing. The short CBX2-2 isoform would repress the transcription in a PRC1-independent fashion, whereas gene repression by the long CBX2-1 isoform is mediated by the PRC1 protein complex. PMID: 22419124
    9. CDYL functions as a molecular bridge between PRC2 and the repressive chromatin mark H3K27me3, forming a positive feedback loop to facilitate the establishment and propagation of H3K27me3 modifications along the chromatin PMID: 22009739
    10. hPc2 serves as a SUMO E3 ligase for cystathionine beta-synthase, increasing the efficiency of sumoylation. PMID: 19107218
