Phospho-CBX3 (Ser93) Antibody

1. c-Myc was capable of upregulating HP1gamma by directly binding to the E-box element in the first intron of HP1gamma gene, and the upregulated HP1gamma, in turn, repressed the expression of miR-451a by enhancing H3K9 methylation at the promoter region of miR-451a. PMID: 28967902

3. CBX3 serves as a positive regulator of aerobic glycolysis via suppressing of the FBP1 in pancreatic cancer cells. PMID: 29678579
4. HP1gamma is present in the nucleus and the cytoplasm interacting with actin, a protein complex that may exert different functions depending on its subcellular localization. PMID: 29208528
5. CBX3 has a role in promoting tumor proliferation by regulating G1/S phase via p21 downregulation and associates with poor prognosis in tongue squamous cell carcinoma PMID: 29462646
6. The deletion of CBX3 directly enforces the expression of CDK6 and p21. PMID: 28193906
7. These data indicate that HP1-gamma is a novel epigenetic repressor of epsilon-globin gene expression. PMID: 28154185
8. these data underscore the importance of IDRs 1, 2, and 3 in defining the structural and dynamic properties of HP1gamma, discoveries that have both mechanistic and potentially biomedical relevance. PMID: 26680990
9. In contrast to HP1alpha, HP1gamma could not recognize H3K9me3 in extended nucleosomes. PMID: 26319017
10. this study identified miR-30a as a tumor-suppressive microRNA that targets HP1gamma in vitro and in vivo to specifically suppress the growth of colorectal cancer in mouse xenograft models. PMID: 26333808
11. BARD1 interacts with H3K9me2 through HP1 and plays a critical role in retention of a BRCA1/BARD1 complex at the site of DNA damage. PMID: 25634209
12. CBX3 and CRABP2 expression was markedly increased in lung cancer tissues PMID: 24751108
13. our data suggested that HP1gamma plays an important role in promoting non-small cell lung cancer PMID: 24981246
14. compartmentalized and total HP1gamma protein expression is increased in PCa and that expression correlates with clinical outcomes better than Gleason score. PMID: 23522301
15. HP1gamma affects the spontaneous differentiation potential of P19 cells, and might play major roles in the decision of cell fates in pluripotent stem cells. PMID: 23313480
16. Identification of CBX3 and ABCA5 as putative biomarkers for tumor stem cells in osteosarcoma. PMID: 22870217
17. Loss of CBX3 results in global RNA processing defect. PMID: 22684280
18. The Cbx3 chromodomain binds with comparable affinities to all of the methylated H3K9, H1K26 and G9aK185 peptides. PMID: 22514736
19. HIV-1 Vpr displaces heterochromatin protein 1-alpha and heterochromatin protein 1-gamma from chromatin, resulting in premature chromatid separation. PMID: 21875947
20. we show distinct cell-type- and cancer-stage-associated patterns of key heterochromatin marks: heterochromatic adaptor proteins HP1alpha and HP1gamma, compared with the gammaH2AX marker of endogenously activated DNA damage response. PMID: 20695923
21. HP1gamma localizes to telomeres in S phase, where it is required to establish/maintain cohesion PMID: 21865325
22. this study reveals that human NIPBL is a novel protein recruited to DSB sites, and the recruitment is controlled by MDC1, RNF168 and HP1gamma. PMID: 21784059
23. The Ca2+ channel beta4c subunit interacts with heterochromatin protein 1 gama via a PXVXL binding motif. PMID: 21220418
24. HP1 gamma binds CD44 pre-mRNA inside the variant region of CD44. PMID: 21358630
25. Under oxidative conditions, HP1gamma dimerized and held TIF1beta in a chromatin component and inhibited its repression ability. PMID: 20675861
26. Pax3 represses transcription through a novel mechanism involving competition between corepressor KAP1 and the heterochromatin-binding protein HP1gamma PMID: 16945326
27. Suv39H1, HP1gamma and histone H3Lys9 trimethylation play a major role in chromatin-mediated repression of integrated HIV-1 gene expression. PMID: 17245432
28. In non-differentiated cells, transcriptional intermediary factor TIF1beta/heterochromatin protein HP1 interaction occurs only within euchromatin and involves selectively HP1beta and HP1gamma, but not HP1alpha. PMID: 17381543
29. Overexpression of HP1-GAMMA in wing imaginal discs caused abnormal wings. PMID: 17575412
30. present an investigation of DNA methylation and histone modification marks across the HNRPA2B1-CBX3 locus in primary peripheral blood mononuclear cells (PBMCs) to characterise the chromatin structure that underlies UCOE activity PMID: 18032920
31. Heterochromatin protein gamma coordinately regulates CCN2/CTGF transcription by interacting with nuclear MMP3. PMID: 18172013
32. the spatial proximities among a constellation of functionally related sites that are found within euchromatic regions of the cell nucleus including: HP1gamma, RNA polymerase II, matrin 3, and SAF-A sites PMID: 18618731
