Deletions of 0.5, 1.2 and 1.7 kb upstream of the
vit-2 translational start sequence did not disrupt daf- 16-dependent repression of
pvit-2:GFP expression in
daf-2(
e1370) hermaphrodites. Thus,
daf-16 regulation of YP requires only a short 300-bp
vit-2 promoter, but not additional upstream sequences.
