The Drosophila histone variant H2A.V works in concert with HP1 to promote kinetochore-driven microtubule formation [PDF]

open access: yes, 2015
Unlike other organisms that have evolved distinct H2A variants for different functions, Drosophila melanogaster has just one variant which is capable of filling many roles.

Biophysical Properties of HP1-Mediated Heterochromatin [PDF]

open access: yesCold Spring Harbor Symposia on Quantitative Biology, 2019
Heterochromatin is a classic context for studying the mechanisms of chromatin organization. At the core of a highly conserved type of heterochromatin is the complex formed between chromatin methylated on histone H3 lysine 9 and HP1 proteins. This type of heterochromatin plays central roles in gene repression, genome stability, and nuclear mechanics ...

Structural basis of HP1/PXVXL motif peptide interactions and HP1 localisation to heterochromatin [PDF]

open access: yesThe EMBO Journal, 2004
HP1 family proteins are adaptor molecules, containing two related chromo domains that are required for chromatin packaging and gene silencing. Here we present the structure of the chromo shadow domain from mouse HP1beta bound to a peptide containing a consensus PXVXL motif found in many HP1 binding partners.

The SENP7 SUMO-Protease Presents a Module of Two HP1 Interaction Motifs that Locks HP1 Protein at Pericentric Heterochromatin

open access: yesCell Reports, 2015
HP1 enrichment at pericentric heterochromatin is essential for proper chromosome segregation. While H3K9me3 is thought to be a major contributor to HP1 enrichment at pericentric domains, in mouse cells, the SUMO-protease SENP7 is required in addition to ...

A monoclonal antibody recognizing very late activation antigen-4 inhibits eosinophil accumulation in vivo. [PDF]

open access: yes, 1993
Using an in vivo test system, the role of the β1 integrin very late activation antigen-4 (VLA-4) in eosinophil accumulation in allergic and nonallergic inflammatory reactions was investigated.

Drosophila RISC component VIG and its homolog Vig2 impact heterochromatin formation. [PDF]

open access: yesPLoS ONE, 2009
Heterochromatin formation plays an important role in gene regulation and the maintenance of genome integrity. Here we present results from a study of the D.

Characterization of a Novel Heterochromatin Protein 1 Homolog “HP1c” in the Silkworm, Bombyx mori

open access: yesInsects, 2022
Heterochromatin protein 1 plays an important role in chromatin structure and gene expression regulation. Three HP1 genes have been found in Homo sapiens, and five HP1 genes have been reported in Drosophila melanogaster. On the other hand, in Bombyx mori,

Mitotic Mysteries: The Case of HP1 [PDF]

open access: yesDevelopmental Cell, 2016
The role of Heterochromatin Protein-1 (HP1) during mitosis has been controversial. Two recent studies in Science and Developmental Cell, from Tanno et al. (2015) and Abe et al. (2016), suggest that the means of HP1 localization and its function at inner centromeres are altered in cancer cells with chromosomal instability.

Liquid droplet formation by HP1α suggests a role for phase separation in heterochromatin. [PDF]

open access: yes, 2017
Gene silencing by heterochromatin is proposed to occur in part as a result of the ability of heterochromatin protein 1 (HP1) proteins to spread across large regions of the genome, compact the underlying chromatin and recruit diverse ligands.

Crystal Structure of the HP1-EMSY Complex Reveals an Unusual Mode of HP1 Binding [PDF]

open access: yesStructure, 2006
Heterochromatin protein-1 (HP1) plays an essential role in both the assembly of higher-order chromatin structure and epigenetic inheritance. The C-terminal chromo shadow domain (CSD) of HP1 is responsible for homodimerization and interaction with a number of chromatin-associated nonhistone proteins, including EMSY, which is a BRCA2-interacting protein ...
