Comments concerning this interaction

Rga was fused to a plasma membrane or ER membrane anchor. The ability of this chimera to recruit prey protein to the plasma membrane was taken as evidence of direct physical interaction.

Source was live S2R+ cells; bait and prey produced from endogenous genes.
