UASt regulatory sequences drive expression of amino acid residues 261-1207 of JIL-1 (lacks the N-terminal domain), tagged at the N-terminal end with lacI(DBD).
JIL-1ΔNTD.Scer\UAS.T:Ecol\lacI restores polytene chromosome morphology in JIL-1z2 mutant animals to or near wild type. Rescue of adult viability is 18.9%.
