Researchers from the Epigenetics and Cancer Biology Program of the Bellvitge Biomedical Research Institute (IDIBELL), led by Dr. Àlex Vaquero, have elucidated the role of HP1 proteins in relation to chromatin structure and genome stability, distinguishing different functions based on the presence of different variants of this protein. The work, published in Cell Reports, was carried out in collaboration with other research groups in Europe and the United States.
