    a Y-fork DNA substrate used to assay activity of XPF-ERCC1 complexes. The preferred cleavage site of XPF-ERCC1 is denoted by an arrow and liberates a 23-nt DNA fragment with a 3’-Cy3 fluorophore used for detection of the product. b Comparison of nuclease activity of XPF-ERCC1, XPF-ERCC1-SLX4IP, XPF-ERCC1-SLX4IP-SLX4 330-555 , and XPF-ERCC1-SLX4 330-555 . Conversion of uncleaved input substrate (a) into product (23-nt fragment) was monitored by detection of Cy3 fluorescence. SLX4IP has no impact on activity, while the presence of SLX4 in the complex increases cleavage, as evidenced by the more rapid disappearance of the band corresponding to the intact substrate.

    Article Snippet: Primary antibodies used were: GFP (Roche Cat# 11814460001, RRID:AB_390913, 1:500), MUS81 (Santa Cruz Biotechnology Cat# sc-47692, RRID:AB_2147129,1:500), ERCC1 (Santa Cruz Biotechnology Cat# sc-17809, RRID:AB_2278023,1:500), SLX4 (MRC-PPU Cat# S714C, RRID:AB_2752254, 1:500), SLX1 (Proteintech Cat# 21158-1-AP, RRID:AB_2752255, 1:500), EME1 (Santa Cruz Biotechnology Cat# sc-393363, 1:500), XPF (Bethyl Cat# A301-315A, RRID:AB_938089 1:500), and SLX4IP (Santa Cruz Biotechnology Cat# sc-377066, RRID:AB_2752253).

    Techniques: Cryo-EM Sample Prep

    a Left: Cryo-EM map of the XPF-ERCC1-SLX4IP-SLX4 330-555 -DNA complex. Three SLX4 segments (orange) are visualised and labelled. Right: Cryo-EM map of the DNA-free complex from the same data collection shown in the same orientation. Only SLX4 residues 526-552 are visualised, in line with the higher-resolution reconstructions shown in Fig. . Maps are shown without any b-factor sharpening applied to facilitate visualisation of weaker densities. b Schematic depiction of the sequence elements and domains contained in the SLX4 constructs used for in vitro endonuclease assays of XPF-ERCC1-SLX4IP-SLX4 complex variants. c In-vitro endonuclease assay comparing the activity of XPF-ERCC1 to the activities of different variants of the XPF-ERCC1-SLX4IP-SLX4 330-555 complex. Conversion of the input substrate (see Fig. ) into 23-nt product was monitored by detection of Cy3 fluorescence. To facilitate visualisation, 10 min time points are marked with a red dot. The removal of the UBZ-2 domain and the addition of the BTB domain do not have an appreciable effect on endonuclease activity. Removal of the sequence elements that are solely visualised in the DNA-bound XPF-ERCC1-SLX4IP-SLX4 330-555 complex strongly reduces cleavage activity. Two additional experimental repeats and all protein sample processing controls are provided in Supplementary Fig. . Source Data are provided as a file.
