Summary: Enables calcium:sodium antiporter activity involved in regulation of cardiac muscle cell membrane potential and protein homodimerization activity. Involved in calcium export from the mitochondrion; intracellular calcium ion homeostasis; and regulation of lymphocyte chemotaxis. Acts upstream of or within mitochondrial calcium ion transmembrane transport and sodium ion transmembrane transport. Located in mitochondrion and plasma membrane. Is expressed in forelimb bud. Orthologous to human SLC8B1 (solute carrier family 8 member B1). [provided by Alliance of Genome Resources, Dec 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.
