Hsp83 upstream sequences up to -170bp, which include a heat shock element (HSE), drive lacZ expression.
lacZ gene expression is driven by a fragment of Hsp83 promoter region from -170 nucleotides from the transcription start point to +1616 which includes the first 108 amino acids.
Carried in plasmid c83Z-170 and expressed in Schneider S2 cells.
