Comments concerning this interaction

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.

(Baëza et al., 2015)

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

Comments concerning this interaction

Source was embryos of transgenic fly line; proteins produced from tagged transgenic constructs.

(Bischof et al., 2018)

An abd-A-kn interaction was not detected when components were fused to YFP.
