PLXNA1
plexin A1 | NOV, PLXN1

Predicted to enable semaphorin receptor activity. Predicted to be involved in several processes, including T cell activation via T cell receptor contact with antigen bound to MHC molecule on antigen presenting cell; nervous system development; and semaphorin-plexin signaling pathway. Predicted to act upstream of or within dichotomous subdivision of terminal units involved in salivary gland branching; neuron projection extension; and regulation of smooth muscle cell migration. Located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Jul 2025]

PLXNA1 — as a Regulated Gene

TFs regulating PLXNA1 0 TFs

Transcription factors with Perturb-seq knockdown data for PLXNA1. 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 = PLXNA1 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 PLXNA1

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of PLXNA1, 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.
