SLC8A2
solute carrier family 8 member A2 | KIAA1087, NCX2

Predicted to enable calcium:monoatomic cation antiporter activity involved in regulation of postsynaptic cytosolic calcium ion concentration and calcium:sodium antiporter activity. Predicted to be involved in several processes, including learning or memory; monoatomic cation transmembrane transport; and regulation of short-term neuronal synaptic plasticity. Predicted to act upstream of or within several processes, including modulation of chemical synaptic transmission; regulation of action potential firing pattern; and response to ischemia. Located in presynapse. Biomarker of Alzheimer's disease. [provided by Alliance of Genome Resources, Jul 2025]

Expression (TPM)
SLC8A2 — as a Regulated Gene

TFs regulating SLC8A2 0 TFs

Transcription factors with Perturb-seq knockdown data for SLC8A2. 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 = SLC8A2 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 SLC8A2

Open chromatin peaks (ATAC-seq) in the genomic neighbourhood of SLC8A2, 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.
