Zinc Finger Database (ZiFDB) v2.0: a comprehensive database of C₂H₂ zinc fingers and engineered zinc finger arrays. [PMID: 23203887]
ZiFDB (Zinc Finger Database, http://zifdb.msi.umn.edu) is a web-accessible database that houses information on individual C(2)H(2) zinc fingers (ZFs) and engineered zinc finger arrays (ZFAs). ZiFDB serves as a resource for biologists interested in engineering ZFAs for use as sequence-specific DNA-binding reagents. Here, we describe four new features of ZiFDB: (i) the database allows users to input new ZFs and ZFAs; (ii) a shadow database temporarily stores user-submitted data, pending approval by the database curator and subsequent loading into the persistent database; (iii) ZiFDB contains 181 Context-Dependent Assembly (CoDA) ZFAs, which were generated by this newly described ZFA engineering platform; and (iv) the database also now contains 319 F1F2 CoDA units and 334 F2F3 CoDA units that can be used to construct CoDA arrays. In total, the new release of ZiFDB contains 1226 ZFs and 1123 ZFAs. |

Zinc Finger Database (ZiFDB): a repository for information on C2H2 zinc fingers and engineered zinc-finger arrays. [PMID: 18812396]
Zinc fingers are the most abundant DNA-binding motifs encoded by eukaryotic genomes and one of the best understood DNA-recognition domains. Each zinc finger typically binds a 3-nt target sequence, and it is possible to engineer zinc-finger arrays (ZFAs) that recognize extended DNA sequences by linking together individual zinc fingers. Engineered zinc-finger proteins have proven to be valuable tools for gene regulation and genome modification because they target specific sites in a genome. Here we describe ZiFDB (Zinc Finger Database; http://bindr.gdcb.iastate.edu/ZiFDB), a web-accessible resource that compiles information on individual zinc fingers and engineered ZFAs. To enhance its utility, ZiFDB is linked to the output from ZiFiT--a software package that assists biologists in finding sites within target genes for engineering zinc-finger proteins. For many molecular biologists, ZiFDB will be particularly valuable for determining if a given ZFA (or portion thereof) has previously been constructed and whether or not it has the requisite DNA-binding activity for their experiments. ZiFDB will also be a valuable resource for those scientists interested in better understanding how zinc-finger proteins recognize target DNA. |
