This suggested that FTZ-F1 might act as a cofactor for FTZ function rather than as a requisite regulator of ftzgene expression. enemy approaching piano easy

"Web1 Jan 2001 · To activate transcription, most nuclear receptor proteins require coactivators that bind to their ligand‐binding domains (LBDs). The Drosophila FTZ‐Factor1 (FTZ‐F1) protein is a conserved member of the nuclear receptor superfamily, but was previously thought to lack an AF2 motif, a motif that is required for ligand and coactivator binding. … " - Ftz mutant embryos
