Ptet Promoter
Tetr repression is inhibited by the addition of tetracycline or its analog atc.
Ptet promoter. Promoter is constitutively on and repressed by tetr. Rather both proteins activate expression. The present invention relates to promoters. The difference between tet on and tet off is not whether the transactivator turns a gene on or off as the name might suggest.
Description of the prior art. In nature the p tet promoter expresses tetr the repressor and teta the protein that pumps tetracycline antibiotic out of the cell. Ptet 1 is composed of a cmv derived minimal promoter linked downstream to an array of seven tet operators. Tetr repressible promoter sequence for ptet inverting regulator.
