TranscriptomicsGlobal analysis of Drosophila Cys2-His2 zinc finger proteins reveals a multitude of novel recognition motifs and binding determinants.
Cys2-His2 zinc finger proteins (ZFPs) are the largest group of transcription factors in higher metazoans. A complete characterization of these ZFPs and their associated target sequences is pivotal to fully annotate transcriptional regulatory networks in metazoan genomes. As a first step in this proc...

TranscriptomicsSequence specificity is obtained from the majority of modular C2H2 zinc-finger arrays
C2H2 zinc fingers (C2H2-ZFs) are the most prevalent type of vertebrate DNA-binding domain, and typically appear in tandem arrays (ZFAs), with sequential C2H2-ZFs each contacting 3 (or more) sequential bases. C2H2-ZFs can be assembled in a modular fashion, providing one explanation for their remarkab...

GenomicsGenome-wide binding profiles of an artificial zinc finger protein with or without a KLF3 functional domain
Transcription factors are often regarded as having two distinct components: a DNA binding domain (DBD) to allow binding to the regulatory region of a target gene and a trans-acting functional domain (FD) to modulate gene expression. Recently, it is becoming clear that the DBDs of transcription facto...

GenomicsSelective Functions of Individual Zinc Fingers Within the DNA-Binding Domain of Ikaros (ChIP-seq: Thymocytes)
The C2H2 zinc finger is the most prevalent DNA-binding motif in the mammalian proteome, with DNA-binding domains usually containing more tandem fingers than are needed for stable sequence-specific DNA recognition. To examine the reason for the frequent presence of multiple zinc fingers, we generated...

TranscriptomicsTranscription profiling of Arabidopsis transgenic seedlings overexpressing MINI ZINC FINGER 1 (MIF1)
Phytohormones play crucial roles in regulating many aspects of plant development. Although much has been learned about the effects of individual hormones, cross-talk between and integration of different hormonal signals are still not well understood. We present a study of MINI ZINC FINGER 1 (MIF1), ...

TranscriptomicsHT-SELEX of recombinant C2H2 zinc finger domains of Sall4
To define the sequence preference of SALL4 C2H2 zinc finger domains, we performed SELEX coupled with high-throughput sequencing (HT-SELEX) using the purified SALL4 ZFC1, ZFC2 and ZFC4 domains combined with no protein control experiment.

TranscriptomicsMultiparameter functional diversity of human C2H2 zinc finger proteins [RNA-Seq]
C2H2 zinc finger proteins represent the largest and most enigmatic class of human transcription factors. Their C2H2 arrays are highly variable, indicating that most will have unique DNA binding motifs. However, most of the binding motifs have not been directly determined. We have determined the bind...
