Comments concerning this interaction

Interaction in embryo; bait produced from tagged transgenic construct; prey produced from tagged transgenic construct.

(Baëza et al., 2015)

To visualize the interaction, both proteins were tagged with a complementary fragment of the Venus fluorophore. Proximity of the two proteins resulted in reconstitution of the fluorescent protein.
