Interaction of human Ku70 with TRF2.

abstract：:A structural tree for proteins and domains containing S-like beta-sheets has been constructed. An S-like beta-sheet is taken as a starting structure in modelling or as a root structure of the tree. Larger structures are obtained by a stepwise addition of beta-strands and/or alpha-helices to the root S-like beta-sheet ...
