Dfd autoregulates itself in cells of mandibular neuromere in embryonic CNS.
Hth shows a region specific role in regulating Dfd expression in embryonic CNS.
Hth is critical for Dfd expression in neuroblasts of maxillary neuromere.
Hth is not important for Dfd neural autoregulation and its role is restricted to regulating levels of Dfd.
Homeodomain-less isoform Hth is sufficient for its role in Dfd regulation in embryonic Nbs.
