Post-translational modificationi
Sumoylated on Lys-164, and to a lesser extent on Lys-127 by the UBC9/SIZ1 complex during S-phase; which impairs ubiquitination and function in DNA repair.3 Publications
Monoubiquitinated on Lys-164 by the UBC2/RAD18 complex upon DNA damage, and then polyubiquitinated through 'Lys-63'-linkage by UBC13/MMS2. Ubiquitination is required for UBC2-mediated DNA repair.1 Publication
Lys-164 is deubiquitinated by UBP10 (PubMed:22829782).1 Publication
