Project description:RNA sequencing was performed to investigate the the response mechanism of tomato response to drought stress. C2H2-type zinc finger proteins are classic and extensively studied members of the zinc finger family. C2H2-type zinc finger proteins participate in plant growth, development and stress responses. In this study, 99 C2H2-type zinc finger protein genes were identified and classified into four groups, and many functionally related cis-elements were identified. Differential C2H2-ZFP gene expression and specific responses were analyzed under drought, cold, salt and pathogen stresses based on RNA-Seq data. Thirty-two C2H2 genes were identified in response to multiple stresses. Seven, 3, 5, and 8 genes were specifically expressed under drought, cold, salt and pathogenic stresses, respectively. Five glycometabolism and sphingolipid-related, pathways and the endocytosis pathway were enriched by KEGG analysis. The results of this study represent a foundation for further study of the function of C2H2-type zinc finger proteins and will provide us with genetic resources for stress tolerance breeding.

Project description: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 binding sites and motifs of 119 C2H2 zinc finger proteins and the expression pattern of 80 cell lines overexpressing C2H2 zinc finger proteins in order to study the role of C2H2 zinc finger proteins in gene regulation.

We expressed GFP-tagged C2H2-ZF proteins in stable transgenic HEK293 cells. Total RNA was isolated using Trizol and sequencing libraries were constructed using TruSeq Stranded Total RNA Library Prep Kit with Ribo-Zero Gold or TruSeq RNA Library Preparation Kit v2.

Project description:To identify targets of the C2H2 zinc finger protein ZINC 34 FINGER OF ARABIDOPSIS THALIANA 14 (ZAT14, AT5G03510), we used an estradiol-inducible system for inducible expression of ZAT14, comparing gene expression in estradiol-treated plants and mock-treated 5-day old seedlings 8 hours after estradiol or mock treatment.

Project description:To investigate the differences in DNA binding specificity of wild-type SALL4 C2H2 zinc finger cluster 4 (ZFC4) and disease causing mutations in SALL4 ZFC4, we performed SELEX coupled with high-throughput sequencing (HT-SELEX) using the purified wild-type SALL4 ZFC4 domain, mutated SALL4 ZFC4 (R900W) and mutated SALL4 ZFC4 (G921D) combined with no protein control experiment.

Project description: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. We re-sequenced the libraries from E-MTAB-9236 with very high coverage to estimate the minimum number of reads required per sample for accurate results.

Project description:This SuperSeries is composed of the SubSeries listed below. Cys2-His2 zinc finger (C2H2-ZF) proteins represent the largest class of putative human transcription factors (TFs). However, it is unknown whether most C2H2-ZFs even bind DNA, or what sequences they bind. Using a combination of bacterial one-hybrid (B1H) assays, protein-binding microarrays (PBMs), and ChIP-seq, we have found that most natural C2H2-ZFs bind DNA both in vitro and in vivo. This SuperSeries contains the data for identification of C2H2-ZF binding preferences using these three approaches. Refer to individual Series

Project description:In Drosophila, a group of zinc finger architectural proteins recruits the CP190 protein to the chromatin, an interaction that is essential for the functional activity of promoters and insulators. In this study, we describe a new architectural C2H2 protein called Madf and Zinc-Finger Protein 1 (Mzfp1) that interacts with CP190. Mzfp1 has an unusual structure that includes six C2H2 domains organized in a C-terminal cluster and two tandem MADF domains. Mzfp1 predominantly binds to housekeeping gene promoters located in both euchromatin and heterochromatin genome regions. In vivo mutagenesis studies showed that Mzfp1 is an essential protein, and both MADF domains and the CP190 interaction region are required for its functional activity. The C2H2 cluster is sufficient for the specific binding of Mzfp1 to regulatory elements, while the second MADF domain is required for Mzfp1 recruitment to heterochromatin. Mzfp1 binds to the proximal part of the Fub boundary that separates regulatory domains of the Ubx and abd-A genes in the Bithorax complex. Mzfp1 participates in Fub functions in cooperation with the architectural proteins Pita and Su(Hw). Thus, Mzfp1 is a new architectural C2H2 protein involved in the organization of active promoters and insulators in Drosophila.
