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.

Biology

previous reported engineered zinc finger-based transcription factors

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

We describe 15 transcriptional activators that display 2- to 463-fold induction and 15 transcriptional repressors that show 1.3- to 16-fold repression.

artificial zinc fingers with modular DNA-binding domains

JJ Collins et al have reported a synthetic biology framework based on orthogonal artificial zinc fingers[2].
