FNDC3B
fibronectin type III domain containing 3B | DKFZp762K137, FAD104, FLJ23399, PRO4979, YVTM2421

Enables RNA binding activity. Predicted to act upstream of or within several processes, including negative regulation of osteoblast differentiation; substrate adhesion-dependent cell spreading; and type II pneumocyte differentiation. Predicted to be located in endoplasmic reticulum. [provided by Alliance of Genome Resources, Jul 2025]

FNDC3B — as a Regulated Gene

TFs regulating FNDC3B 0 TFs

Transcription factors with Perturb-seq knockdown data for FNDC3B. 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 = FNDC3B 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 FNDC3B

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of FNDC3B, 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.
