Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>-Experimental evidence at transcript leveli <p>This indicates the type of evidence that supports the existence of the protein.

Mitochondrial sodium/calcium antiporter that mediates sodium-dependent calcium efflux from mitochondrion, by mediating the exchange of 3 sodium ions per 1 calcium ion (PubMed:20018762, PubMed:28445457).

Plays a central role in mitochondrial calcium homeostasis by mediating mitochondrial calcium extrusion: calcium efflux is essential for mitochondrial function and cell survival, notably in cardiomyocytes (PubMed:24067497, PubMed:28445457).

Regulates rates of glucose-dependent insulin secretion in pancreatic beta-cells during the first phase of insulin secretion: acts by mediating efflux of calcium from mitochondrion, thereby affecting cytoplasmic calcium responses (By similarity).

Required for store-operated Ca2+ entry (SOCE) and Ca2+ release-activated Ca2+ (CRAC) channel regulation: sodium transport by SLC8B1 leads to promote calcium-shuttling that modulates mitochondrial redox status, thereby regulating SOCE activity (By similarity).

Involved in B-lymphocyte chemotaxis (PubMed:27328625).

Able to transport Ca2+ in exchange of either Li+ or Na+, explaining how Li+ catalyzes Ca2+ exchange (By similarity).

In contrast to other members of the family its function is independent of K+ (By similarity).

Caution

Isoform 1 was reported to not have cation exchanger activity (PubMed:12080145). However, such result is unclear.1 Publication
Isoform 1 and isoform 2 were reported to localize to the endoplasmic reticulum membrane and cell membrane, respectively (PubMed:14625281). This result is however not supported by other studies that report localization to the mitochondrial membrane (PubMed:20018762, PubMed:24067497).3 Publications

Conditional deletion in adult hearts causes sudden death in 87% of the mice. Hearts show substantial cardiac remodeling, including an increase in heart mass and correlative change in cardiomyocyte cross-sectional area, as well as a significant increase in cardiac fibrosis. Defects are probably due to mitochondrial calcium overload leading to increased generation of superoxide and necrotic cell death.1 Publication
