Biochemical and in vivo studies over the past several decades have implied that the diverse functions of heterochromatin rely on the ability of these structures to spread across. In eukaryotic cells, structures called heterochromatin play critical roles in nuclear processes ranging from gene repression to chromosome segregation.

Figure 1 | hp1a exhibits liquid demixing in vitro and in vivo. Heterochromatin is a transcriptionally silent chromatin domain in eukaryotes that is essential for genome stability and gene expression regulation.

In Eukaryotic Cells, Structures Called Heterochromatin Play Critical Roles In Nuclear Processes Ranging From Gene Repression To Chromosome Segregation.

Constitutive heterochromatin is made of repetitive sequences and is epigenetically identified by methylation of h3k9 and binding of heterochromatin protein 1a (hp1a). We propose that emergent biophysical. Biochemical and in vivo studies over the past several decades have implied that the diverse functions of heterochromatin rely on the ability of these structures to spread across.

It has recently been suggested that heterochromatin can form by phase separation through the local accumulation of hp1α 16, 17. Constitutive heterochromatin is an important component of eukaryotic genomes that has essential roles in nuclear architecture,. After dissolution of droplets on ice, bugz underwent the same degree of phase transition upon warming, indicating that the phase separation was repeatable (figure 3g).
