Predicted to be a structural constituent of synapse-associated extracellular matrix. Predicted to be involved in GABAergic synaptic transmission; nervous system development; and skeletal system development. Predicted to be located in extracellular region. Predicted to be active in extracellular space; perineuronal net; and synapse. [provided by Alliance of Genome Resources, Jul 2025]
Transcription factors with Perturb-seq knockdown data for HAPLN4. 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 = HAPLN4 upregulated upon KD; negative = downregulated). The Outlier column indicates whether this gene is in the top or bottom 5% of all TF knockdown effects.
| TF | Mean coef | Binding | Outlier | TF→Gene link |

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of HAPLN4, 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.
| Accessibility | Element | Dist. to TSS | Link type | TFs |

Genomic view of the HAPLN4 locus showing ATAC-seq accessibility and RNA-seq expression across the ESC → DE time course, together with TF binding peaks and element-to-TSS loop connections.
