Comments concerning this interaction

Two-hybrid system: yeast GAL4-BD/GAL4-AD

Source was yeast cell line; bait produced as transgenic fusion protein; prey produced as transgenic fusion protein (prey was previously cloned reagent).

nopo interacted with DNApol-η and DNApol-ι, but not with Rev1 (inconclusive), in yeast two hybrid assays.
