<http://identifiers.org/uniprot/P57103> <http://www.biopax.org/release/biopax-level3.owl#comment> "FUNCTION: Rapidly transports Ca(2+) during excitation-contraction coupling. Ca(2+) is extruded from the cell during relaxation so as to prevent overloading of intracellular stores (By similarity). ENZYME REGULATION: By intracellular calcium ions (By similarity). SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein. ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=6; Name=3; Synonyms=NCX3.3; IsoId=P57103-1; Sequence=Displayed; Name=2; Synonyms=NCX3.2; IsoId=P57103-2; Sequence=VSP_008116; Name=4; Synonyms=NCX3.4; IsoId=P57103-3; Sequence=VSP_008117, VSP_008118; Note=May be produced at very low levels due to a premature stop codon in the mRNA, leading to nonsense-mediated mRNA decay. No experimental confirmation available; Name=5; Synonyms=NCX3-tN.1; IsoId=P57103-4; Sequence=VSP_043125; Note=Expressed in fetal brain; Name=6; Synonyms=NCX3-tN.2; IsoId=P57103-5; Sequence=VSP_043126, VSP_008116; Note=Expressed in fetal brain; Name=7; IsoId=P57103-6; Sequence=VSP_043850; TISSUE SPECIFICITY: Isoform 2 is expressed in brain and skeletal muscle. Isoform 3 is expressed in excitable cells of brain, retina and skeletal muscle. Isoform 4 is expressed in skeletal muscle. SIMILARITY: Belongs to the sodium/potassium/calcium exchanger family. SLC8 subfamily. SIMILARITY: Contains 2 Calx-beta domains. GENE SYNONYMS:SLC8A3 NCX3. COPYRIGHT: Protein annotation is derived from the UniProt Consortium (http://www.uniprot.org/).
