CLSTN3
calsyntenin 3 | CDHR14, CSTN3, KIAA0726

Enables cell-cell adhesion mediator activity and neurexin family protein binding activity. Involved in L-ascorbic acid metabolic process and regulation of synapse assembly. Predicted to be located in several cellular components, including Golgi membrane; dendrite; and postsynaptic density. Predicted to be part of protein-containing complex. Predicted to be active in several cellular components, including GABA-ergic synapse; lipid droplet; and postsynaptic density membrane. [provided by Alliance of Genome Resources, Apr 2025]

CLSTN3 — as a Regulated Gene

TFs regulating CLSTN3 0 TFs

Transcription factors with Perturb-seq knockdown data for CLSTN3. 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 = CLSTN3 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 CLSTN3

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of CLSTN3, 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.
