CNBP Transcription Factor
CCHC-type zinc finger nucleic acid binding protein | CNBP1, RNF163, ZCCHC22, DM2, ZNF9

This gene encodes a nucleic-acid binding protein with seven zinc-finger domains. The protein has a preference for binding single stranded DNA and RNA. The protein functions in cap-independent translation of ornithine decarboxylase mRNA, and may also function in sterol-mediated transcriptional regulation. A CCTG expansion from <30 repeats to 75-11000 repeats in the first intron of this gene results in myotonic dystrophy type 2. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2016]

Genes regulated by CNBP

Genes likely regulated by CNBP through linked binding evidence in open chromatin. The chart ranks TF-linked genes by their mean Perturb-seq response to CNBP knockdown, with negative coefficients indicating downregulation and positive coefficients indicating upregulation upon knockdown.

Regulatory Elements bound by the TF

Open chromatin elements (ATAC-seq) where CNBP has ChIP-seq or motif footprint binding evidence and which are linked to at least one target gene region.

CNBP — as a Regulated Gene

TFs regulating CNBP 0 TFs

Transcription factors with Perturb-seq knockdown data for CNBP. The Binding column indicates whether any binding evidence exists for this TF–gene pair (ChIP-seq or motif footprint peaks). The Mean coef is the average Perturb-seq regression coefficient across active gRNAs (positive = CNBP upregulated upon KD; negative = downregulated). The Outlier column indicates whether this gene is in the top or bottom 5% of all TF knockdown effects.

Elements linked to CNBP

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of CNBP, linked by TSS proximity or chromatin conformation (Multiome / HiCAR). Each element overlaps at least one TF ChIP-seq binding site — the TFs column shows how many distinct TFs bind that element.
