Regulation of PNKP and XRCC4 in non-homologous end-joining by dynamic, reversible protein phosphorylation.
EF 2011-12
Résumé
Ionizing radiation (IR) is used extensively in the treatment of many forms of cancer. It acts by inducing lethal DNA damage, in particular a form called a DNA double strand break or DSB. The major pathway for the repair of IR-induced DSBs in human cells is called non-homologous end-joining or NHEJ. We have identified IR-induced modifications of two of the key proteins in NHEJ: XRCC4 and PNKP. This grant explains how we will characterize these modifications to understand how they regulate how cells repair IR-induced DSBs. This work will help us to understand the basic processes by which cells detect and repair IR-induced DNA damage and could lead to better treatments for cancer patients.
