Description
| - DNA repair events have functional significance especially for genome stability. Although the DNA damage response within the whole genome has been extensively studied, the region-specific characteristics of nuclear sub-compartments such as the nucleolus or fragile sites have not been fully elucidated. Here, we show that the heterochromatin protein HP1 and PML protein recognize spontaneously occurring 53BP1- or gamma-H2AX-positive DNA lesions throughout the genome. Moreover, 53BP1 nuclear bodies, which co-localize with PML bodies, also occur within the nucleoli compartments. Irradiation of the human osteosarcoma cell line U2OS with gamma-rays increases the degree of co-localization between 53BP1 and PML bodies throughout the genome; however, the 53BP1 protein is less abundant in chromatin of ribosomal genes and fragile sites (FRA3B and FRA16D) in gamma-irradiated cells.
