Adaptive evolution drives the diversification of zinc-finger binding domains.
The human genome is estimated to contain 700 zinc-finger genes, which perform many key functions, including regulating transcription. The dramatic increase in the number of these genes as we move from yeast to C. elegans to Drosophila and to humans, as well as the clustered organization of these genes in humans, suggests that gene duplication has played an important role in expanding this famil...
متن کاملIn-depth study of DNA binding of Cys2His2 finger domains in testis zinc-finger protein
Previously, we identified that both fingers 1 and 2 in the three Cys2His2 zinc-finger domains (TZD) of testis zinc-finger protein specifically bind to its cognate DNA; however, finger 3 is non-sequence-specific. To gain insights into the interaction mechanism, here we further investigated the DNA-binding characteristics of TZD bound to non-specific DNAs and its finger segments bound to cognate ...
متن کاملStructure-based design of an RNA-binding zinc finger.
A structure-based approach was used to design RNA-binding zinc fingers that recognize the HIV-1 Rev response element (RRE). An arginine-rich alpha-helix from HIV-1 Rev was engineered into the zinc finger framework, and the designed fingers were shown to bind specifically to the RRE with high affinity and in a zinc-dependent manner, and display cobalt absorption and CD spectra characteristic of ...
متن کاملSolution Structure of an Archaeal DNA Binding Protein with an Eukaryotic Zinc Finger Fold
While the basal transcription machinery in archaea is eukaryal-like, transcription factors in archaea and their viruses are usually related to bacterial transcription factors. Nevertheless, some of these organisms show predicted classical zinc fingers motifs of the C2H2 type, which are almost exclusively found in proteins of eukaryotes and most often associated with transcription regulators. In...
متن کاملZiFiT (Zinc Finger Targeter): an updated zinc finger engineering tool
ZiFiT (Zinc Finger Targeter) is a simple and intuitive web-based tool that provides an interface to identify potential binding sites for engineered zinc finger proteins (ZFPs) in user-supplied DNA sequences. In this updated version, ZiFiT identifies potential sites for ZFPs made by both the modular assembly and OPEN engineering methods. In addition, ZiFiT now integrates additional tools and res...
