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).

Weak interaction.

Interaction in vitro; bait produced as a recombinant fusion protein in bacterial system; prey produced and labeled by in vitro translation.

SAK was de-phosphorylated by PpD3 prior to binding reaction with Cp110.
