Comments concerning this interaction

Bait protein was fused to an outer mitochondrial membrane anchor, which targets the chimera to mitochondria. The ability of this chimera to recruit prey protein to mitochondria was taken as evidence of direct physical interaction.

Source was S2 cell line; bait produced from tagged transfected construct; prey produced from transfected construct.
