A conserved DNA sequence cluster from the tbrd-2 gene (length: 849bp, conserved bases: 367bp) is fused upstream of a minimal Hsp70 promoter driving expression of the GAL4 open reading frame.
ScerGAL4CG7229.5 activates expression in a subset of neuroblasts during late sub-lineage development. Expression partially overlaps with that of ScerGAL4cas.6. Expression is not detected at larval or adult stages.
