Additional Information
Statement
Reference

Embryonic expression is observed in the future medial and lateral neuroblasts of row B.

(Skeath et al., 1994)

Expression is similar to that of endogenous ac, and is observed in sensory mother cells and associated clusters of the wing disc. Expression is also observed in the wing pouch of the wing disc.
