Structural basis of specific H2A K13/K15 ubiquitination by RNF168
Abstract
Ubiquitination of histone H2A can occur on distinct lysine residues, but how each site is recognised by the specific E3 ligase remains poorly understood. Here the authors demonstrate that the E3 ligase RNF168 binds the acidic patch on the nucleosome surface, directing the E2 to the target lysine K13/K15.
