CIAO3
cytosolic iron-sulfur assembly component 3 | FLJ21988, HPRN, IOP1, NAR1, PRN, NARFL

Predicted to enable 4 iron, 4 sulfur cluster binding activity and metal ion binding activity. Involved in several processes, including intracellular oxygen homeostasis; iron-sulfur cluster assembly; and response to hypoxia. Part of cytosolic [4Fe-4S] assembly targeting complex.

CIAO3 — as a Regulated Gene

TFs regulating CIAO3 0 TFs

Transcription factors with Perturb-seq knockdown data for CIAO3. 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 = CIAO3 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 CIAO3

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of CIAO3, 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.
