In most eukaryotes, constitutive heterochromatin is associated with H3K9me3 and HP1 alpha. The latter has been shown to play a role in heterochromatin formation through liquid-liquid phase separation. However, many other proteins are known to regulate and/or interact with constitutive heterochromatic regions in several species. We postulate that some of these heterochromatic proteins may play a role in the regulation of heterochromatin formation by liquid-liquid phase separation. Indeed, an analysis of the constitutive heterochromatin proteome shows that proteins associated with constitutive heterochromatin are significantly more disordered than a random set or a full nucleome set of proteins. Interestingly, their expression begins low and increases during preimplantation development. These observations suggest that the preimplantation embryo is a useful model to address the potential role for phase separation in heterochromatin formation, anticipating exciting research in the years to come.
