Summary: This gene encodes a member of the sodium/calcium exchanger integral membrane protein family. Na+/Ca2+ exchange proteins are involved in maintaining Ca2+ homeostasis in a wide variety of cell types. The protein is regulated by intracellular calcium ions and is found in both the plasma membrane and intracellular organellar membranes, where exchange of Na+ for Ca2+ occurs in an electrogenic manner. Alternative splicing has been observed for this gene and multiple variants have been described. [provided by RefSeq, Aug 2013]

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.

Description

Transcript Variant: This variant (g, also known as NCX3-tN.2) differs in the presence and absence of exons at its 5' end, compared to variant c. These differences result in a distinct 5' UTR and translation initiation at a downstream start codon, and an isoform (G) that is shorter than isoform C.

Status: REVIEWED

Description

Transcript Variant: This variant (h) lacks two alternate internal exons, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant c, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
