ZF21.16-VP64

This part is one of the downstream elements of our amplifier. Zinc finger 21.16 (Part:BBa_K2549046) is a synthetic engineered DNA binding domain with high sequence specificity and high orthogonality with other zinc finger proteins. VP64 (Part:BBa_K1982012) is a tetrameric VP16 transcription activator which shows ultrahigh transcription activation function. A SV40NLS domain (Part:BBa_K2549054) is placed on the N terminal of VP64 to guide the fusion protein to enter in the nucleus. A G4S linker (Part:BBa_K2549053) is set between ZF21.16 and SV40NLS. This part can also be utilized by other iGEM teams as zinc finger-based transcription activators to construct their own genetic circuits.

previous reported engineered zinc finger-based transcription factors

Jason J. Lohmueller et al has reported a tunable zinc finger-based transcription framework in mammalian cells[1].

Zinc finger-based transcription activator. Jason J. Lohmueller et al stated:We generate ZF-TF activators and repressors and demonstrate a novel, general method to tune ZF-TF response by fusing ZF-TFs to leucine zipper homodimerization domains. We describe 15 transcriptional activators that display 2- to 463-fold induction and 15 transcriptional repressors that show 1.3- to 16-fold repression.
