靶點詳情

  • 功能：
    Seems to be involved in transcriptional silencing in heterochromatin-like complexes. Recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression. May contribute to the association of the heterochromatin with the inner nuclear membrane through its interaction with lamin B receptor (LBR). Involved in the formation of functional kinetochore through interaction with MIS12 complex proteins. Contributes to the conversion of local chromatin to a heterochromatin-like repressive state through H3 'Lys-9' trimethylation, mediates the recruitment of the methyltransferases SUV39H1 and/or SUV39H2 by the PER complex to the E-box elements of the circadian target genes such as PER2 itself or PER1. Mediates the recruitment of NIPBL to sites of DNA damage at double-strand breaks (DSBs).
  • 基因功能參考文獻：
    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
    2. CBX3 was overexpressed in pancreatic adenocarcinoma, which was associated with poor prognosis. CDK1 knockdown attenuated the cell cycle transition, proliferation and invasion of CBX3-overexpressing PAAD cells. PMID: 29903985
    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

    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
