In-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 کاملProtein Delivery Using Cys<sub>2</sub>His<sub>2</sub> Zinc-Finger Domains
The development of new methods for delivering proteins into cells is a central challenge for advancing both basic research and therapeutic applications. We previously reported that zinc-finger nuclease proteins are intrinsically cell-permeable due to the cell-penetrating activity of the Cys2−His2 zinc-finger domain. Here, we demonstrate that genetically fused zincfinger motifs can transport pro...
متن کاملPredicting DNA recognition by Cys2His2 zinc finger proteins
MOTIVATION Cys(2)His(2) zinc finger (ZF) proteins represent the largest class of eukaryotic transcription factors. Their modular structure and well-conserved protein-DNA interface allow the development of computational approaches for predicting their DNA-binding preferences even when no binding sites are known for a particular protein. The 'canonical model' for ZF protein-DNA interaction consis...
متن کاملSynthetic protein–protein interaction domains created by shuffling Cys2His2 zinc-fingers
Cys2His2 zinc-fingers (C2H2 ZFs) mediate a wide variety of protein-DNA and protein-protein interactions. DNA-binding C2H2 ZFs can be shuffled to yield artificial proteins with different DNA binding specificities. Here we demonstrate that shuffling of C2H2 ZFs from transcription factor dimerization zinc-finger (DZF) domains can also yield two-finger DZFs with novel protein-protein interaction sp...
متن کاملProfiling the DNA-binding specificities of engineered Cys2His2 zinc finger domains using a rapid cell-based method
The C2H2 zinc finger is the most commonly utilized framework for engineering DNA-binding domains with novel specificities. Many different selection strategies have been developed to identify individual fingers that possess a particular DNA-binding specificity from a randomized library. In these experiments, each finger is selected in the context of a constant finger framework that ensures the i...
