TRE Promoter with Tet operators
This is TRE promoter with Tet operators. This is useful for driving reporter transcription in Tet-on pathways, such as the TANGO assay. In Tet-on pathways, release of tTA will result in downstream transcription from this promoter.

Our project aims at expressing AID in hybridoma cells. Since AID is a deaminase that would induce point mutation, the expression of AID should be tightly regulated. In order to achieve this purpose, we incorporate Tet-on system, an inducible protein expression system, into our design. When tetracycline is added, it combined with rtTA (reverse tetracycline-controlled transactivator) to form a rtTA-tetracycline complex, which can recognize and attach to TetO sequence and express our target protein. By this approach, our construct is able to regulate the amount of AID expressed. However, excessive rtTA may pose harm to cells, so people can’t turn off the tet-on system too late.
