These data reveal that 53BP1 is phosphorylated on multiple residues in response to different types of DNA damage, and that 53BP1 is regulated by ATR in response to UV-induced DNA damage

:
53BP1 bystander foci were induced in an ATR dependent manner predominantly in S-phase cells, similar to gammaH2AX foci induction
