  • 功能：
    Component of heterochromatin. Recognizes and binds histone H3 tails methylated at 'Lys-9', leading to epigenetic repression. Interaction with lamin B receptor (LBR) can contribute to the association of the heterochromatin with the inner nuclear membrane.
  • 基因功能参考文献：
    1. the prolyl residue of the PXXVXL motif appears to play a role distinct from that of Pro in the known HP1beta CSD-PXVXL complexes. PMID: 28223359
    2. Data show that heterochromatin protein 1-beta (HP1beta) is a prototypic HP1 protein exemplifying most basal chromatin binding and effects. PMID: 27090491
    3. increased HP1beta expression is associated with the poor prognosis in breast cancer PMID: 25769025
    4. In this review, we summarize the current knowledge about targeting and functional mechanisms of PRCs, emphasizing the recent breakthroughs related to CBX proteins under a number of physiological and pathological conditions. PMID: 24793759
    5. Data suggest the reduction of Heterochromatin Protein 1 isoforms HP1beta followed by a decrease in HP1alpha contributes to the pathogenesis of thyroid carcinomas, and their loss is a potential marker of thyroid malignancy and metastatic potential, respectively. PMID: 24840329
    6. Phosphorylation at Ser89 and Ser175 results in localized conformational changes in HP1beta that do not compromise the ability of the protein to bind chromatin. PMID: 24561199
    7. HP1 isoforms distinctly augment AR signaling and cell growth in prostate cancer. Therefore, silencing of HP1beta and HP1gamma may be a promising therapeutic strategy for treatment of prostate cancer. PMID: 23536649
    8. The structural plasticity of HP1beta supports its ability to bind and connect a wide variety of binding partners in epigenetic processes. PMID: 23585859
    9. HP1beta which is associated with PCNA in regions of DNA repair, is bound and does not exchange with the mobile pool, suggesting that HP1beta in association with PCNA may be a component of a DNA repair complex. PMID: 23337132
    10. The HP1beta interactome is enriched with Lys methylated proteins.Role of HP1beta in DNA damage response. PMID: 23707759
    11. study finds that while HP1apha and beta stimulate homologous recombination and single-strand annealing, HP1gamma has an inhibitory role PMID: 23287531
    12. Methylation of lysine 9 in histone H3 directs alternative modes of highly dynamic interaction of heterochromatin protein hHP1beta with the nucleosome PMID: 22815475
    13. HP1 beta and PCNA, a key player in DNA replication, are closely spaced components of a multiprotein complex involved in replication, both in S phase and during DNA repair, and that the functional complex requires formation of an HP1 dimer. PMID: 22617335
    14. Abrogating GRP/GRPR signaling specifically down-regulates HP1(Hsbeta) expression and inhibiting GRPR signaling, or ablating HP1(Hsbeta) expression, increases colon cancer cell invasiveness in vitro. PMID: 21281799
    15. HP1beta is involved in the proliferation of AR-expressing prostate cancer cells and progression to CRPC as an AR coactivator. PMID: 20308360
    16. Isoform-specific interaction of HP1 with human TAFII130. PMID: 11959914
    17. Gene regulation by human orthologs of Drosophila heterochromatin protein 1. PMID: 12054505
    18. the chromodomain and the chromoshadow domain of HP1 are both required for binding to native chromatin in vivo, but they contribute differentially to binding in euchromatin and heterochromatin PMID: 12560555
    19. cells are exquisitely sensitive to the amount of HP1(Hsalpha) or HP1(Hsbeta) present, as their overexpression influences telomere stability, population doubling time, radioresistance, and tumorigenicity PMID: 14585993
    20. HP1beta recruits endogenous HP1alpha to the chromatin and this induces heterochromatin formation and enhanced histone lysine methylation. PMID: 15899859
    21. analysis of methylation-independent binding to histone H3 and cell cycle-dependent incorporation of HP1beta into heterochromatin PMID: 16547356

    23. Overexpression of HP1-BETA in eye imaginal discs caused abnormally patterned eyes, with reduced numbers of ommatidia. PMID: 17575412
    24. HP1 recruitment-release is a sequential mechanism that is precisely regulated and highly dependent on transcription. PMID: 18239689
    25. findings reveal an unrecognized signalling cascade that helps to initiate the DNA damage response, altering chromatin by modifying a histone-code mediator protein, HP1, but not the code itself PMID: 18438399
    26. when HP1beta was co-expressed with TIF1beta/S473A, but not TIF1beta/S473E, the colocalization of TIF1beta/S473A and HP1beta to the promoters of Cdc2 and Cdc25A was enhanced. PMID: 18590578
    27. a nonconventional interaction between HP1 and a tissue-specific transcription factor, MyoD. In addition, they strongly suggest that HP1 isoforms play important roles during muscle terminal differentiation in an isoform-dependent manner. PMID: 18599480
