A- Y2H analysis of interactions between full length SLX4 fused to the GAL4-AD and full length or truncated SLX1 fused to the GAL4-DBD.
B- Y2H analysis of interactions between full length SLX1 fused to GAL4-DBD and various SLX4 truncations fused to GAL4-AD.
C- Immunoprecipitation of the indicated FLAG-tagged SLX1 proteins overproduced in HEK cells along with the indicated GFP-tagged SLX4 proteins. Western blot shows FLAG-tagged SLX1, GFP-tagged SLX4 and endogenous XPF in total cell lysates and FLAG-eluates. The amount of total cell lysate loaded per lane is 10% of the input, relative to the amount loaded of the corresponding FLAG-eluate.
D- Y2H analysis of interactions between SLX4 and SLX1 fused to GAL4-AD and XPF and ERCC1 fused to GAL4-DBD.
E- Y2H analysis of interaction between XPF fused to GAL4-DBD and the indicated SLX4 fragments fused to GAL4-AD.
