The Proteomic Composition and Organization of Constitutive Heterochromatin in Mouse Tissues. [PDF]

open access: yesCells
Pericentric heterochromatin (PCH) forms spatio-temporarily distinct compartments and affects chromosome organization and stability. Albeit some of its components are known, an elucidation of its proteome and how it differs between tissues in vivo is lacking.

The analysis of pendolino (peo) mutants reveals differences in the fusigenic potential among Drosophila telomeres [PDF]

open access: yes, 2015
Drosophila telomeres are sequence-independent structures that are maintained by transposition to chromosome ends of three specialized retroelements (HeT-A, TART and TAHRE; collectively designated as HTT) rather than telomerase activity. Fly telomeres are

Stress-induced activation of heterochromatic transcription. [PDF]

open access: yesPLoS Genetics, 2010
Constitutive heterochromatin comprising the centromeric and telomeric parts of chromosomes includes DNA marked by high levels of methylation associated with histones modified by repressive marks.

Cytologic characterization of human constitutive heterochromatin

open access: bronze, 2000
A study was conducted to cytologically map certain subsets of constitutive heterochromatin onto specific portions of human chromosomes. This involved sequentially staining metaphase chromosomes from lymphocytes first with the Centromeric Dot, Giemsa-11, G-banding or Lateral Asymmetry staining techniques, which are cytochemical methods which stain ...

Suv39h1 links the SUMO pathway to constitutive heterochromatin. [PDF]

open access: yesMol Cell Oncol, 2016
The Suv39h lysine methyltransferases, known as key enzymes responsible for histone H3 lysine 9 methylation, are critical for heterochromatin protein 1 enrichment at constitutive heterochromatin. Our recent findings reveal a new role for the Suv39h1 paralog that links it to SUMO pathway function at constitutive heterochromatin.

Chromosome mapping of dragline silk genes in the genomes of widow spiders (araneae, theridiidae) [PDF]

open access: yes, 2010
With its incredible strength and toughness, spider dragline silk is widely lauded for its impressive material properties. Dragline silk is composed of two structural proteins, MaSp1 and MaSp2, which are encoded by members of the spidroin gene family ...

On the evolution of Yeti, a Drosophila melanogaster heterochromatin gene. [PDF]

open access: yesPLoS ONE, 2014
Constitutive heterochromatin is a ubiquitous and still unveiled component of eukaryotic genomes, within which it comprises large portions. Although constitutive heterochromatin is generally considered to be transcriptionally silent, it contains a ...

The replacement histone H2A.Z in a hyperacetylated form is a feature of active genes in the chicken [PDF]

open access: yes, 2005
The replacement histone H2A.Z is variously reported as being linked to gene expression and preventing the spread of heterochromatin in yeast, or concentrated at heterochromatin in mammals.

On the relations of phase separation and Hi-C maps to epigenetics [PDF]

open access: yesRoyal Society Open Science, 2020
The relationship between compartmentalization of the genome and epigenetics is long and hoary. In 1928, Heitz defined heterochromatin as the largest differentiated chromatin compartment in eukaryotic nuclei.
