Summary: Enables calcium:monoatomic cation antiporter activity involved in regulation of postsynaptic cytosolic calcium ion concentration and calcium:sodium antiporter activity. Involved in monoatomic cation transmembrane transport; response to vitamin D; and telencephalon development. Acts upstream of or within intracellular calcium ion homeostasis. Located in several cellular components, including dendritic spine; microtubule; and neuronal cell body. Is active in postsynaptic membrane. Biomarker of brain ischemia and status epilepticus. Orthologous to human SLC8A2 (solute carrier family 8 member A2). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
