Fig. 5. N-EGF12f is a functional receptor, but cannot rescue DV boundary formation.
Wing discs stained for expression of WG (magenta), with MARCM clones
expressing a Notch receptor under tub-Gal4 control and mutant for the
endogenous Notch gene identified by GFP (green). (A)
N55e11; tub-Gal4 UAS-GFP UASN.865. Notch
activation is continuous through a clone that spans the DV border (arrow). (B)
N55e11; tub-Gal4 UAS-GFP
UAS-NEGF12f[M4a]. Notch is activated ectopically within a dorsal clone
(arrow). (C) N55e11; tub-Gal4 UAS-GFP
UAS-N-EGF12f[M4a]. Notch activation is disrupted at the DV boundary
(arrowhead).
