Comments concerning this interaction

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

Rcd-1 (CAF40) preferentially associates with Not1 over other components of the CCR-NOT complex (Rga, Not3, Pop2 and twin).

Comments concerning this interaction

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

Not3 was fused to a plasma membrane anchor. The ability of this chimera to recruit prey protein to the plasma membrane was taken as evidence of direct physical interaction.
