E3 ubiquitin-protein ligase HERC2 (HERC2)

E3 ubiquitin-protein ligase that regulates ubiquitin- dependent retention of repair proteins on damaged chromosomes. Recruited to sites of DNA damage in response to ionizing radiation (IR) and facilitates the assembly of UBE2N and RNF8 boosting DNA damage-induced formation of'Lys-63'-linked ubiquitin chains.

Acts as a mediator of binding specificity between UBE2N and RNF8. Involved in the maintenance of RNF168 levels.
