2. HP1-alpha oligomerization is critical to the maintenance of heterochromatin and the tunable dynamics of this HP1 isoform. PMID: 26238434
3. demonstrate an actin-driven differential modulation of core histone H2B and heterochromatin HP1alpha protein dynamics with chromatin PMID: 26359759
4. the molecular behavior of HP1alpha throughout the cell cycle PMID: 25036950
5. There is a functional link between prelamin A, HP1alpha, chromatin remodeling, DNA repair, and early senescence in Zmpste24-deficient mice, suggesting a potential therapeutic strategy for laminopathy-based premature aging via the intervention of HP1alpha. PMID: 24584199
6. the TIF1beta-HP1 system functions as a critical repressive machinery that targets genes not normally activated in the hematopoietic compartment, thereby maintaining the transcriptional signature specific to HSCs. PMID: 24527388
7. HP1 mobility in apoptotic cells appeared to be unique. PMID: 23023195
8. Elimination of HP1alpha by siRNA interfered with centromere relocation from heterochromatin surrounding NPBs to pro-chromocenters at the two-cell stage but did not affect preimplantation develoment to the blastocyst stage. PMID: 22622086
9. Depletion of Senp7 delocalizes HP1 alpha from pericentric heterochromatin without affecting H3K9me3 levels. PMID: 22388734
10. The interplay between MU2 and HP1a is dynamic and may be different in euchromatin and heterochromatin during DNA break recognition and repair. PMID: 21966530
11. KAP1 and HP1 tether activation-induced cytidine deaminase (AID) to H3K9me3 residues at the donor switch region, thus linking AID to epigenetic modifications during class switch recombination. PMID: 21746811
12. Our findings suggest that H4K20me3 and HP1-alpha are markers for cell type commitment that can be triggered by developmental or cell context, independently of the differentiation process PMID: 21576353
13. The HP1alpha recruitment at early stages of the DDR involves p150CAF-1 and is critical for proper DNA damage signaling and repair. PMID: 21464229
14. Hp1a was multiply phosphorylated at N-terminal serine residues (S11-14) in human and mouse cells and this phosphorylation enhanced its affinity for K9-methylated histone H3. PMID: 21245376
15. post-gastrulation development, but not for Sertoli cell functions during spermatogenesis. PMID: 21163256
16. The 3sFRET microscopy method was then applied to study the interactions of the dimeric transcription factor C/EBPalpha (expressing mTFP or mVenus) with the heterochromatin protein 1alpha (HP1alpha, expressing tdTomato) in live-mouse pituitary cells. PMID: 20713013
17. quantitative description of HP1alpha/beta in terms of its concentration, diffusion coefficient, kinetic binding, and dissociation rate constants PMID: 19948116
18. The scFv fragments can recognize both CD motifs of HP1 and Polycomb (Pc) in vitro and, when expressed intracellularly, interact with and dislodge the HP1 protein(s) from their heterochromatin localization in vivo. PMID: 11956312
19. Data provide evidence for nuclear compartmentalization of transcriptional intermediary factor 1 beta (TIF1beta) that is regulated during cell differentiation through a mechanism that requires heterochromatin protein 1 interaction. PMID: 12154074
20. HP1alpha has separate domains that recognize histone H3 tails and RNA PMID: 12231507
21. Data suggest that self-interaction through the chromo shadow domain of heterochromatin protein 1 alpha is crucial for recruitment of SUV39H1 onto nucleosomes. PMID: 12565857
22. Molecular explanation for the functional link of these epigenetic silencing processes mediated by Su(z)12 PMID: 14570930
23. HP1alpha interacts with the preRC proteins ORC1, ORC2 and CDC6; results together indicate that HP1alpha plays a role in mitosis and cytokinesis PMID: 16950245
24. Knockdown of SUZ12 in human cells caused a reduction in H3K27me3 and H3K9me3, and altered the distribution of HP1 alpha. PMID: 17406994
25. epigenetic regulations orchestrated by HP1 isoforms, are critical for permanent cell cycle exit during neuronal differentiation PMID: 17627279
26. the Suv39h-HP1 pathway is not essential for enrichment and mitotic protection of cohesin at centromeres in mammalian cells PMID: 18075750
27. TRIM28 interaction with HP1 is absolutely required for the primer binding site -dependent restriction of murine leukemia virus in the F9 EC cell line. PMID: 18287239
28. H3K9me3 and HP1alpha recruitment to retrotransposons occurs independent of DNA methylation in ES cells and G9a promotes DNA methylation independent of its HMTase activity PMID: 18818693
