Drosophila melanogaster heat-shock protein 70 (Hsp70) promoter
Drosophila Hsp70 promoter (~468 bp); heat-inducible via heat shock factor binding to HSEs upon a shift to 37°C; near-zero basal activity at permissive temperatures. Allows precise temporal control of transgene expression in Drosophila.
Characteristics
Heat-inducible Pol II promoter activated at 37°C via heat shock factor binding to HSEs. Near-zero basal activity; allows precise temporal control of transgene expression in Drosophila.
