Integrated multi-omics analysis of zinc finger proteins uncovers roles in RNA regulation

ABSTRACT: RNA interactome studies have revealed that hundreds of zinc-finger proteins (ZFPs) are candidate RNA-binding proteins (RBPs), yet their RNA substrates and functional significance remain largely uncharacterized. Here, we present a systematic multi-omics analysis of the DNA- and RNA-binding targets and regulatory roles of more than 100 ZFPs representing 37 zinc-finger families. We show that multiple ZFPs are previously unknown regulators of RNA splicing, alternative polyadenylation, stability, or translation. The examined ZFPs show widespread sequence-specific RNA binding and preferentially bind proximal to transcription start sites. Additionally, several ZFPs associate with their targets at both the DNA and RNA levels. We highlight ZNF277, a C2H2 ZFP that binds thousands of RNA targets and acts as a multi-functional RBP. We also show that ZNF473 is a DNA/RNA-associated protein that regulates the expression and splicing of cell cycle genes. Our results reveal diverse roles for ZFPs in transcriptional and post-transcriptional gene regulation.

Integrated multi-omics analysis of zinc finger proteins uncovers roles in RNA regulation [Ribo-STAMP cell lines]

Project description:RNA interactome studies have revealed that hundreds of zinc finger proteins (ZFPs) are candidate RNA-binding proteins (RBPs), despite being annotated as DNA-interacting transcription factors. The RNA substrates of ZFPs and the functional significance of their potential roles as DNA- and RNA-binding proteins (DRBPs) remain largely uncharacterized. Here we present a systematic multi-omics analysis of the DNA and RNA binding targets and regulatory roles of more than 100 ZFPs representing 37 zinc finger families. We show that multiple ZFPs are novel regulators of RNA splicing, polyadenylation, or stability. The examined ZFPs show widespread sequence-specific RNA binding ability and preferentially bind proximal to transcription start sites. Additionally, several ZFPs are DRBPs that bind their targets at both the DNA and RNA levels. We highlight ZNF277, a C2H2 ZFP that binds thousands of RNA targets and acts as a multi-functional RBP. We also show that ZNF473 is a DRBP that regulates the expression and splicing of cell cycle genes. Our results reveal diverse roles for ZFPs in transcriptional and post-transcriptional gene regulation, shedding light on a large class of under-studied RBPs.

Global analysis of Drosophila Cys2-His2 zinc finger proteins reveals a multitude of novel recognition motifs and binding determinants.

Project description: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 process, we have characterized the DNA-binding specificities of 130 Zinc finger sets from Drosophila melanogaster using a bacterial one-hybrid system. This data set contains the DNA-binding specificities for at least one encoded ZFP from 71 unique genes and 22 alternate splice isoforms. This represents the largest block of characterized ZFPs from any organism described to date. These recognition motifs can be used to predict genomic binding sites and potential regulatory targets for these factors within the fruit fly genome. We have characterized subsets of fingers from these ZFPs to define the correct orientation and register of the zinc fingers on their defined binding sites. By correlating individual fingers with motif subsites, we can assign finger specificity throughout each ZFP. This reveals the diversity of recognition potential within the naturally-occurring zinc fingers of a single organism, where the characterized fingers can specify 47 of the 64 possible DNA triplets. To confirm the utility of our finger recognition models, we have employed subsets of Drosophila fingers in combination with an existing archive of zinc finger modules to create ZFPs with novel DNA-binding specificity. These finger combinations can be used to create novel functional Zinc Finger Nucleases for editing vertebrate genomes. Illumina sequencing of Barcoded Binding sites obtained after B1H selection of Cys2-His2 zinc finger proteins cloned as a C-terminal fusions to the omega subunit of E. coli RNA polymerase in the B1H system.

Role of Ikaros in Early B-cell Development: Studies of IkZnF1-/- and IkZnF4-/- mutant mice

Project description:Ikaros is a zinc finger (ZnF) transcription factor critical for B-cell development. 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 mice lacking finger 1 or finger 4 of the 4-finger DNA-binding domain of Ikaros (Schjerven et al., Nat Immunol, 2013; PMID: 24013668). Each mutant strain exhibited a specific subset of the phenotypes observed with Ikaros null mice, and revealed that different subsets of fingers within multi-finger transcription factors can regulate distinct target genes and biological functions. We here study the effect of these mutants on early B-cell development in the bone marrow (BM) with transcriptome profiling of sorted proB-cells (Hardy fractions B+C+C') from BM of wt and the two ZnF mutants (this GEO submission: RNA-Seq).

Selective Functions of Individual Zinc Fingers Within the DNA-Binding Domain of Ikaros (RNA-seq: sorted DP thymocytes)

Project description: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 mice lacking finger 1 or finger 4 of the 4-finger DNA-binding domain of Ikaros, a critical regulator of lymphopoiesis and leukemogenesis. Each mutant strain exhibited a specific subset of the phenotypes observed with Ikaros null mice. Of particular relevance, fingers 1 and 4 contributed to distinct stages of B- and T-cell development and finger 4 was selectively required for tumor suppression in thymocytes and in a new model of BCR-ABL+ acute lymphoblastic leukemia. These results, combined with transcriptome profiling (this GEO submission: RNA-Seg of whole thymus from wt and the two ZnF mutants), reveal that different subsets of fingers within multi-finger transcription factors can regulate distinct target genes and biological functions, and they demonstrate that selective mutagenesis can facilitate efforts to elucidate the functions and mechanisms of action of this prevalent class of factors.
