PLXNA3
plexin A3 | 6.3, Plxn3, SEX, XAP-6, PLXN4

This gene encodes a member of the plexin class of proteins. The encoded protein is a class 3 semaphorin receptor, and may be involved in cytoskeletal remodeling and as well as apoptosis. Studies of a similar gene in zebrafish suggest that it is important for axon pathfinding in the developing nervous system. This gene may be associated with tumor progression.

PLXNA3 — as a Regulated Gene

TFs regulating PLXNA3 0 TFs

Transcription factors with Perturb-seq knockdown data for PLXNA3. 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 = PLXNA3 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 PLXNA3

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of PLXNA3, 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.
