ZIC3 Transcription Factor
Zic family zinc finger 3 | HTX, ZNF203, HTX1

This gene encodes a member of the ZIC family of C2H2-type zinc finger proteins. This nuclear protein probably functions as a transcription factor in early stages of left-right body axis formation. Mutations in this gene cause X-linked visceral heterotaxy, which includes congenital heart disease and left-right axis defects in organs. [provided by RefSeq, Jul 2008]

Genes regulated by ZIC3

Genes likely regulated by ZIC3 through linked binding evidence in open chromatin. The chart ranks TF-linked genes by their mean Perturb-seq response to ZIC3 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 ZIC3 has ChIP-seq or motif footprint binding evidence and which are linked to at least one target gene region.

ZIC3 — as a Regulated Gene

TFs regulating ZIC3 0 TFs

Transcription factors with Perturb-seq knockdown data for ZIC3. 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 = ZIC3 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 ZIC3

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of ZIC3, 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.
