NEIL3 Zf-GRF motifs interact with different ssDNA structures.
A–C, EMSA show the interaction between ssDNA39 and GST-NEIL3-ZF1&2, GST-NEIL3-ZF1, or GST-NEIL3-ZF1&2 K553A at different doses as indicated at room temperature for 60 min. D-F, EMSA reveal interaction between ssDNA39-AP and increased concentrations of GST-NEIL3-ZF1&2 or GST-NEIL3-ZF1 or GST-NEIL3-ZF1&2 K553A in vitro. G-I, interaction between ssDNA70 and GST-NEIL3-ZF1&2 or GST-NEIL3-ZF1 but not with GST-NEIL3-ZF1&2 K553A via EMSA.
