Description

UASt regulates expression of full length D fused to the en repressor domain (amino acids 1-298). This acts as a dominant negative protein.

      Reference

      Scer\GAL4sim.P3.7- or Scer\GAL4pros.C20-mediated expression of DScer\UAS.T:Rep-en results in embryos with collapsed commissures, reduced separation between longitudinal tracts, gaps in longitudinal connectives, misrouting and inappropriate midline crossing by longitudinal axons. 50-70% of embryos exhibit some degree of CNS disruption.

      The strong embryonic CNS defects of Dr72/Df(3L)fz-GS1a animals are made worse when DScer\UAS.T:Rep-enis expressed via Scer\GAL4sim.P3.7 in this background.
