Figure 1 Base Excision Repair Complex Formation and Regulation by Posttranslational Modification Model depicting DNA damage-initiated recruitment of the scaffold protein XRCC1-Lig III and subsequent recruitment of Pol β for the formation of a productive BER complex. Proteins not in a repair complex are subject to CHIP-mediated ubiquitylation and degradation. Question marks underlie the impact of Pol β or XRCC1 PTMs that might alter BER complex formation and CHIP-mediated ubiquitylation as a potential mode for crosstalk to govern BER capacity.
