Structure of the Ku heterodimer bound to DNA and its implications for double-strand break repair.
J.R.Walker, R.A.Corpina, J.Goldberg.
 
  ABSTRACT  
 
The Ku heterodimer (Ku70 and Ku80 subunits) contributes to genomic integrity through its ability to bind DNA double-strand breaks and facilitate repair by the non-homologous end-joining pathway. The crystal structure of the human Ku heterodimer was determined both alone and bound to a 55-nucleotide DNA element at 2.7 and 2.5 A resolution, respectively. Ku70 and Ku80 share a common topology and form a dyad-symmetrical molecule with a preformed ring that encircles duplex DNA. The binding site can cradle two full turns of DNA while encircling only the central 3-4 base pairs (bp). Ku makes no contacts with DNA bases and few with the sugar-phosphate backbone, but it fits sterically to major and minor groove contours so as to position the DNA helix in a defined path through the protein ring. These features seem well designed to structurally support broken DNA ends and to bring the DNA helix into phase across the junction during end processing and ligation.

Figure 2.
Figure 2: Structure of the Ku-DNA complex. a, View down the DNA helix. Ku70 is coloured red and Ku80 orange. Only the 14-bp duplex portion of DNA is shown; the sugar-phosphate backbone is coloured light grey and the bases dark grey. b, Side view. Black line indicates the molecular dyad axis. Terminal base pairs are numbered +8 (broken DNA end) and -6. c, Abbreviated topology diagram showing the fold of Ku70 and Ku80. Green rods indicate -helices; blue arrows indicate -strands. d, Stereo difference electron density map viewed down the molecular dyad axis (white symbol). Blue contour lines show electron density at the 2.4 -level in a |F[o]| - |F[c]| (2.5 Å resolution) map calculated after simulated-annealing refinement of a model lacking nucleotides from levels -2 to +6 of the 34-residue oligonucleotide.
Figure 4.
Figure 4: Surface depictions of Ku. a, Space-filling model showing Ku bound to DNA. The model was prepared by fitting a 32-bp B DNA to the crystallographically observed duplex. DNA extends towards the viewer to the +11 level. Ku70 is coloured red and Ku80 orange. DNA is shown with one light grey and one dark grey strand. b, Molecular surface representation of Ku is coloured according to electrostatic potential, calculated using the program GRASP44. Negative potential is coloured red and positive potential blue.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
