Comments concerning this interaction

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

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.
