Proteins used to screen compounds for REV1/UbPCNA interaction inhibition. A: REV1 (1251 AA) and its truncated variant (REV1Δ, 695 AA), which was used to screen chemical compounds for inhibiting REV1/UbPCNA interaction. Dotted lines indicate the truncation to generate REV1Δ. B: In vitro production of K164-UbPCNA tagged with a biotin on the ubiquitin N-terminus. The reaction mixtures were analyzed by Coomassie-staining (left) or immunoblotting for pan-PCNA (right, PC-10 antibody) to confirm the UbPCNA bands.
