... of caudal genes is achieved through the function of Headless (Hdl),a Tcf3 homolog. In this study, we show that a second Tcf3 homolog, Tcf3b,limits caudalization caused by loss of Hdl function and although this Lef/Tcf family member can rescue hdl mutants, Lef1 cannot. Wnts can antagonize repression mediated...

... by Eyeless and generates headless flies, which suggests that Eyeless is necessary for initiating cell proliferation and development of both the eye and antennal disc. Interference occurs through a block in the cell cycle that for some ectopic transcription factors is overcome by D-CycE or D-Myc. Late ectopic...
