This intronless gene encodes a member of the SOX (SRY-related HMG-box) family of transcription factors involved in the regulation of embryonic development and in the determination of the cell fate. The encoded protein may act as a transcriptional regulator after forming a protein complex with other proteins, such as syndecan binding protein (syntenin). The protein may function in the apoptosis pathway leading to cell death as well as to tumorigenesis and may mediate downstream effects of parathyroid hormone (PTH) and PTH-related protein (PTHrP) in bone development. The solution structure has been resolved for the HMG-box of a similar mouse protein. [provided by RefSeq, Jul 2008]
Modules significantly affected by knockdown. ↑ Up = module upregulated upon KD; ↓ Down = module downregulated upon KD.

Genes likely regulated by SOX4 through linked binding evidence in open chromatin. The chart ranks TF-linked genes by their mean Perturb-seq response to SOX4 knockdown, with negative coefficients indicating downregulation and positive coefficients indicating upregulation upon knockdown.
Open chromatin elements (ATAC-seq) where SOX4 has ChIP-seq or motif footprint binding evidence and which are linked to at least one target gene region.
| Element | Size | Linked genes |
|---|
Transcription factors with Perturb-seq knockdown data for SOX4. 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 = SOX4 upregulated upon KD; negative = downregulated). The Outlier column indicates whether this gene is in the top or bottom 5% of all TF knockdown effects.

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of SOX4, 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.
