8*ZF43.8-CMV

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. CMV (Part:BBa_K2549050) is a promotor which has a high-level constitutive expression. This part can switch off the expression of gene downstream after induced by our zinc finger-based transcription repressor.

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[1].

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.
