FSTL4
follistatin like 4 | KIAA1061

Predicted to enable brain-derived neurotrophic factor binding activity and calcium ion binding activity. Predicted to be involved in cell differentiation and regulation of BMP signaling pathway. Predicted to act upstream of or within negative regulation of brain-derived neurotrophic factor receptor signaling pathway; negative regulation of collateral sprouting; and negative regulation of dendritic spine development. Predicted to be located in secretory granule. Predicted to be active in extracellular region. [provided by Alliance of Genome Resources, Jul 2025]

FSTL4 — as a Regulated Gene

TFs regulating FSTL4 0 TFs

Transcription factors with Perturb-seq knockdown data for FSTL4. 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 = FSTL4 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 FSTL4

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of FSTL4, 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.
