IQSEC1
IQ motif and Sec7 domain ArfGEF 1 | ARF-GEP100, BRAG2, GEP100, KIAA0763

Predicted to enable protein kinase binding activity. Predicted to be involved in several processes, including positive regulation of focal adhesion disassembly; positive regulation of keratinocyte migration; and regulation of postsynaptic neurotransmitter receptor internalization. Located in centrosome; cytosol; and nucleoplasm. Implicated in intellectual developmental disorder with short stature and behavioral abnormalities and lung adenocarcinoma. Biomarker of lung non-small cell carcinoma. [provided by Alliance of Genome Resources, Jul 2025]

IQSEC1 — as a Regulated Gene

TFs regulating IQSEC1 0 TFs

Transcription factors with Perturb-seq knockdown data for IQSEC1. 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 = IQSEC1 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 IQSEC1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of IQSEC1, 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.
