Summary: Enables calcium:sodium antiporter activity. Involved in several processes, including learning or memory; monoatomic cation transmembrane transport; and nervous system development. Acts upstream of or within several processes, including hematopoietic progenitor cell differentiation; modulation of chemical synaptic transmission; and negative regulation of protein serine/threonine kinase activity. Located in several cellular components, including mitochondrial outer membrane; postsynaptic density; and sarcolemma. Is expressed in several structures, including bone; brain; foregut; genitourinary system; and trachea. Orthologous to human SLC8A3 (solute carrier family 8 member A3).

NCX2 and NCX3 protein and mRNA levels are relatively reduced in hippocampal CA1 of APP23 and APP-KI mice. Likewise, NCX2(+/-) or NCX3(+/-) mice exhibited impaired hippocampal LTP and memory-related behaviors.

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.
