After abasic (AP) residue (5'dRP) is excised by POLB, which is accompanied by dissociation of APEX1 from the DNA, POLB recruits XRCC1:LIG3 complex, consisting of DNA repair protein XRCC1 and DNA ligase 3, to the DNA containing a single nucleotide gap (Nazarkina et al. 2007). The N-terminus of XRCC1 interacts with POLB, while the C-terminus of XRCC1 interacts with LIG3 (Kubota et al. 1996).
