Fig 3. Fusion of CIC to a heterologous DNA binding domain bypasses the requirement for C1.

Fig 3

(A) Structure of Drosophila CIC and CIC derivatives in which the HMG-box has been replaced by the bHLH domain of Hairy. The CIC(bHLH) and CIC(bHLH)ΔC1 proteins are tagged with the HA epitope and are thus discernable from endogenous CIC. (B) Expression of CIC(bHLH)-HA in embryos stained with anti-HA antibody. The inset shows a higher magnification view of nuclear CIC(bHLH)-HA accumulation. (C-E) Sxl mRNA expression in female wild-type (C) and transgenic embryos expressing CIC(bHLH) (D) and CIC(bHLH)ΔC1 (E). Sxl appears clearly repressed in both transgenic embryos.
