Description

Three copies of the 21bp ftz homeodomain binding site (HDS) oriented away from the Hsp70 promoter are fused upstream of the promoter sequences.

(Nelson and Laughon, 1993)

Three tandem copies of a synthetic ftz binding site are fused, in the antisense orientation, upstream of an Hsp70 promoter driving lacZ expression.
