D160N maintains interactions with BER binding partners. A pull-down experiment was performed using WCE from Pol β-deficient MEFs and his-tagged purified Pol β enzyme as described in Section 2. (A) WT and D160N interact with XRCC1 (90 kDa). Lane 1, 25% input; Lane 2, WT with nickel beads alone; Lane 3, D160N with nickel beads alone; Lane 4, WCE with nickel beads alone; Lane 5, WT and WCE pull-down; Lane 6, D160N and WCE pulldown. (B) WT and D160N interact with LigaseIIIα (103 kDa). Lane 1, 25% input; Lane 2, WT with nickel beads alone; Lane 3, D160N with nickel beads alone; Lane 4, WCE with nickel beads alone; Lane 5, WT and WCE pulldown; Lane 6, D160N and WCE pulldown.
