Pericentric heterochromatin (PCH) is a specific type of constitutive heterochromatin that is localized to both sides of centromeres and therefore types silent compartments enriched in repressive marks. These genomic regions contain species-specific repeated satellite DNA that differs in terms of nucleotide sequences and repeat lengths. Regardless of this series variety, PCH is involved with numerous biological phenomena which can be conserved among types, including centromere purpose, the
