Predicted to enable chemorepellent activity; neuropilin binding activity; and semaphorin receptor binding activity. Predicted to be involved in several processes, including axon guidance; neural crest cell migration; and semaphorin-plexin signaling pathway. Predicted to be located in membrane and synapse. Predicted to be active in glutamatergic synapse and postsynaptic density membrane. [provided by Alliance of Genome Resources, Apr 2025]
Transcription factors with Perturb-seq knockdown data for SEMA4B. 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 = SEMA4B 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 SEMA4B, 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.
