Genome mapping and characterization of the
Background Heterochromatin plays an important role in chromosome function and gene regulation. Despite the availability of polytene chromosomes and genome sequence, the heterochromatin of the major malaria vector Anopheles gambiae has not been mapped and

NUP-1 Is a large coiled-coil nucleoskeletal protein in trypanosomes with lamin-like functions. [PDF]
A unifying feature of eukaryotic nuclear organization is genome segregation into transcriptionally active euchromatin and transcriptionally repressed heterochromatin.

A model of dynamic stability of H3K9me3 heterochromatin to explain the resistance to reprogramming of differentiated cells [PDF]
Despite their dynamic nature, certain chromatin marks must be maintained over the long term. This is particulary true for histone 3 lysine 9 (H3K9) trimethylation, that is involved in the maintenance of healthy differentiated cellular states by preventing inappropriate gene expression, and has been recently identified as the most efficient barrier to ...

H3K9 methylation (H3K9me) is a conserved marker of heterochromatin, a transcriptionally silent chromatin structure. Knowledge of the mechanisms for regulating heterochromatin distribution is limited.

SETDB1 regulates microtubule dynamics
SETDB1 association with microtubules inhibits microtubule polymerization and enhances their instability. SETDB1 may affect the microtubules by interacting with HDAC6 to enhance HDAC6 tubulin deacetylation activity. Abstract Objectives SETDB1 is a methyltransferase responsible for the methylation of histone H3‐lysine‐9, which is mainly related to ...

MeCP2 heterochromatin organization is modulated by arginine methylation and serine phosphorylation
Rett syndrome is a human intellectual disability disorder that is associated with mutations in the X-linked MECP2 gene. The epigenetic reader MeCP2 binds to methylated cytosines on the DNA and regulates chromatin organization.

HP1 recruitment in the absence of argonaute proteins in Drosophila. [PDF]
Highly repetitive and transposable element rich regions of the genome must be stabilized by the presence of heterochromatin. A direct role for RNA interference in the establishment of heterochromatin has been demonstrated in fission yeast.

Affinity, stoichiometry and cooperativity of heterochromatin protein 1 (HP1) binding to nucleosomal arrays [PDF]
Heterochromatin protein 1 (HP1) participates in establishing and maintaining heterochromatin via its histone modification dependent chromatin interactions. In recent papers HP1 binding to nucleosomal arrays was measured in vitro and interpreted in terms of nearest-neighbor cooperative binding. This mode of chromatin interactions could lead to spreading
