    Mammalian MDC1 interacts with CHK2 in the regulation of DNA damage-induced S-phase checkpoint and apoptosis, which is directed by the association of MDC1-FHA and CHK2-pThr68. However, different ligand specificities of MDC1-FHA have been reported, and no structure is available. Here we report the crystal structures of MDC1-FHA and its complex with a CHK2 peptide containing pThr68. Unlike other FHA domains, MDC1-FHA exists as an intrinsic dimer in solution and in crystals. Structural and binding analyses support pThr+3 ligand specificity and provide structural insight into MDC1-CHK2 interaction.
