Part:BBa_K2549028

8*ZF43.8-minCMV

This part is one of the response elements of our amplifier, also executing the combiner function. 8*ZF43.8 binding sites is assembled using two 4*ZF43.8 binding sites (Part:BBa_K2446006) with a biobrick scar between them. Minimal CMV (Part:BBa_K2549049) is a promotor providing very low basal expression and high maximal expression after induction. This part can switch on the expression of gene downstream after induced by our zinc finger-based transcription activator.

Biology

synthetic promotor operators regulated by artificial zinc finger-based transcription factors

JJ Collins et al have reported several synthetic promotor operators which can interact with artificial zinc finger-based transcription factors with high specificity and high orthogonality.

JJ Collins et al stated:sTFs constructed from OPEN-engineered ZFs are orthogonal to one another. sTF43-8 activated noncognate Promoter21-16 due to the fortuitous creation of a sequence that is significantly similar to the binding sequence of 43-8, when the downstream BamHI restriction site is considered.
