Structure of tumor suppressor p53 and its intrinsically disordered N-terminal transactivation domain.

abstract：:Resequencing or reference-based assemblies reveal large parts of the small-scale sequence variation. However, they typically fail to separate such local variation into colinear and rearranged variation, because they usually do not recover the complement of large-scale rearrangements, including transpositions and inver...
