Comments concerning this interaction

Source was larval wing discs of transgenic fly line; bait produced from tagged transgenic construct; prey produced from transgenic construct.

Bait protein was fused to the motor domain of kinesin heavy chain (Khc), which targets the chimera to the plus end of microtubules. The ability of this chimera to recruit prey protein to the plus end of microtubules was taken as evidence of direct physical interaction.
