TRE-3G promoter+SV40 PolyA, an ideal controller of mammalian gene expression with Tet-On 3G protein
TRE-3G promoter(PTRE3G) is a kind of eukaryocyte cell promoters that will be switched on after combine with the compound of Tet-On 3G(BBa_K1431101) protein and doxycycline(Dox) mix.
The inducible promoter TRE3G provides for very low basal expression and high maximal expression after induction (Loew et. al., 2010). It consists of 7 repeats of a 19 bp tet operator sequence located upstream of a minimal CMV promoter. In the presence of Dox, Tet-On 3G binds specifically to PTRE3G and activates transcription of the downstream gene of interest (GOI). PTRE3G lacks binding sites for endogenous mammalian transcription factors, so it is virtually silent in the absence of induction.(Source: Clontech)
transactivator undergoes a conformational change allowing it to bind tet operator (tetO) repeats within the
TREG Promoter. The transactivator activates expression through transcription activation domain repeats.
