Source was yeast cell line; bait produced as transgenic fusion protein; prey produced as transgenic fusion protein (prey was previously cloned reagent).
Two-hybrid system: yeast GAL4-BD/GAL4-AD. BDGP clone LD34489, representing FBgn0050420, contains sequences for both Atf-2 and CG44247. It is unclear which of the two sequences is responsible for the observed interaction.
