Fig. 7. Tcf/pan may function as a nuclear anchor for Arm. Confocal microscope images of embryos showing endogenous Arm protein (N2, green) and nuclei (Hoechst, Blue). (A) 67.15; {Delta}Arm, dTCF{Delta}N embryos show a lack of nuclear accumulation of endogenous Arm expected from {Delta}Arm alone. (B) 67.15; dTCF{Delta}N embryos also show a lack of nuclear accumulation. (C) 67.15; dTCF (full length) embryos do not show nuclear accumulation of endogenous Arm protein.
