Np95 Is Implicated in Pericentromeric Heterochromatin Replication and in Major Satellite Silencing [PDF]

, 2006
Heterochromatin plays an important role in transcriptional repression, for the correct segregation of chromosomes and in the maintenance of genome stability.

Ubc9‐Mediated SUMOylation of RPL3, an Unappreciated Mechanism against Hepatocyte Senescence by Repressing the DHX9‐p16 Axis

Advanced Science, EarlyView.
Liver aging is characterized by a decline in the expression of the SUMO‐conjugating enzyme Ubc9, resulting in reduced SUMOylation levels in hepatocytes, particularly in the case of ribosomal protein RPL3. Disruption of RPL3 SUMOylation increases its nuclear translocation. Interestingly, ribosome‐free RPL3 facilitates the recruitment of helicase DHX9 to

HP1 loses its chromatin clustering and phase separation function across evolution

Nature Communications
Heterochromatin protein 1 (HP1) is a multifunctional chromatin-associated protein conserved from fission yeast to mammals. HP1 has been suggested to drive heterochromatin formation via phase separation.

Citrullination of HP1γ chromodomain affects association with chromatin

Epigenetics & Chromatin, 2019
Background Stem cell differentiation involves major chromatin reorganisation, heterochromatin formation and genomic relocalisation of structural proteins, including heterochromatin protein 1 gamma (HP1γ). As the principal reader of the repressive histone

Positional changes of pericentromeric heterochromatin and nucleoli in postmitotic Purkinje cells during murine cerebellum development [PDF]

, 2004
Previous studies revealed changes of pericentromeric heterochromatin arrangements in postmitotic Purkinje cells (PCs) during postnatal development in the mouse cerebellum (Manuelidis, 1985; Martou and De Boni, 2000). Here, we performed vibratome sections

Temporal Stretch‐Induced Nuclear Mechanosensing Coordinates Early Chromatin Accessibility and Genome Protection

Advanced Science, EarlyView.
Cyclic stretching of fibroblasts triggers coordinated nuclear mechanosensing events, including calcium ion release, perinuclear actin assembly, emerin translocation, and H3K9me3 loss, increasing chromatin accessibility for specific genes related to mechanotransduction and repair.

HP1a recruitment to promoters is independent of H3K9 methylation in Drosophila melanogaster.

PLoS Genetics, 2012
Heterochromatin protein 1 (HP1) proteins, recognized readers of the heterochromatin mark methylation of histone H3 lysine 9 (H3K9me), are important regulators of heterochromatin-mediated gene silencing and chromosome structure. In Drosophila melanogaster

Allelic Variation in Maize Malate Dehydrogenase 7 Shapes Promoter Methylation and Banded Leaf and Sheath Blight Resistance

Advanced Science, EarlyView.
In this study maize chloroplastic malate dehydrogenase7 (ZmMDH7), is identified as a Rhizoctonia solani resistance gene in maize. ZmMDH7 is regulated by transcription factor ZmWRKY44 via pathogens challenge to elevate mitochondrial ROS and SA signaling pathway.

HP1B is a euchromatic Drosophila HP1 homolog with links to metabolism. [PDF]

PLoS ONE, 2018
Heterochromatin Protein 1 (HP1) proteins are an important family of chromosomal proteins conserved among all major eukaryotic lineages. While HP1 proteins are best known for their role in heterochromatin, many HP1 proteins function in euchromatin as well.

The Mbd1-Atf7ip-Setdb1 pathway contributes to the maintenance of X chromosome inactivation. [PDF]

, 2014
BackgroundX chromosome inactivation (XCI) is a developmental program of heterochromatin formation that initiates during early female mammalian embryonic development and is maintained through a lifetime of cell divisions in somatic cells.
