SysZNF: the C2H2 zinc finger gene database
C2H2 zinc finger (C2H2-ZNF) genes are one of the largest and most complex gene super-families in metazoan genomes, with hundreds of members in the human and mouse genome. The ongoing investigation of this huge gene family requires computational support to catalog genotype phenotype comparisons of C2H2-ZNF genes between related species and finally to extend the worldwide knowledge on the evoluti...
متن کاملZinc Finger Database (ZiFDB) v2.0: a comprehensive database of C2H2 zinc fingers and engineered zinc finger arrays
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 in...
متن کاملZinc Finger Database (ZiFDB): a repository for information on C2H2 zinc fingers and engineered zinc-finger arrays
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 t...
متن کاملClassification of C2H2 Zinc Finger Domains Using Support Vector Machines
Zinc finger proteins include nuclear receptors for steroid hormones and are mainly DNA-binding transcription factors. Thus those are supposed to be target proteins for drug discovery. C2H2 zinc finger gene family is one of the most popular and complex superfamilies. C2H2 zinc finger domains are composed of approximately 25 to 30 amino acid residues including the paired cysteines and histidines ...
متن کاملSpecific RNA binding by a single C2H2 zinc finger.
Zinc finger proteins with high affinity for human immunodeficiency virus Rev responsive element stem loop IIB (RRE-IIB) were previously isolated from a phage display zinc finger library. Zinc fingers from one of these proteins, RR1, were expressed individually and assayed for RRE-IIB affinity. The C-terminal zinc finger retained much of the binding affinity of the two-finger parent and was disr...
