  "summary": "HP1 proteins are highly evolutionarily conserved chromatin-associated factors known to play essential roles in genome stability and nuclear organization. In mammals, three HP1 isoforms, HP1, HP1{beta} and HP1{gamma}, have been described, but their individual functions remain incompletely characterized. Here, we inactivated HP1 or HP1{beta} in different cell lines and quantified chromosomal breaks…",
