27090491 Data show that heterochromatin protein 1-beta (HP1beta) is a prototypic HP1 protein exemplifying most basal chromatin binding and effects.
25769025 increased HP1beta expression is associated with the poor prognosis in breast cancer
24840329 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.
24793759 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.
24561199 Phosphorylation at Ser89 and Ser175 results in localized conformational changes in HP1beta that do not compromise the ability of the protein to bind chromatin.
23707759 The HP1beta interactome is enriched with Lys methylated proteins.Role of HP1beta in DNA damage response.
23585859 The structural plasticity of HP1beta supports its ability to bind and connect a wide variety of binding partners in epigenetic processes.
23536649 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.
23337132 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.
23287531 study finds that while HP1apha and beta stimulate homologous recombination and single-strand annealing, HP1gamma has an inhibitory role
