Drives expression in the pattern of h, including in a pair rule expression pattern in embryos, and anterior to the morphogenetic furrow in third instar larvae.
Early embryonic expression is observed in every other segment.
Expressed in the endogenous h expression pattern.
In third larval instar eye disc, expressed in a wide band of cells ahead of the morphogenetic furrow.
Expression of GAL4 in imaginal discs first observed at mid-second instar.
Expression delayed relative to wild-type h expression.
