53BP1 binds to the tumor suppressor protein p53 and has a potential role in DNA damage responses.
Small interfering RNA (siRNA) directed against 53BP1 in mammalian cells to demonstrated that 53BP1 is a key transducer of the DNA damage checkpoint signal.
53BP1 was required for p53 accumulation, G2-M checkpoint arrest, and the intra-S-phase checkpoint in response to ionizing radiation.
53BP1 played a partially redundant role in phosphorylation of the downstream checkpoint effector proteins Brca1 and Chk2 but was required for the formation of Brca1 foci in a hierarchical branched pathway for the recruitment of repair and signaling proteins to sites of DNA damage.
