Rabbit anti-Human SLC8B1 Polyclonal Antibody

Uniprot Id

Q6J4K2

Target Species

Human

Target Name

SLC8B1

Target Full Name

Mitochondrial sodium/calcium exchanger protein

Target Function

Mitochondrial sodium/calcium antiporter that mediates sodium-dependent calcium efflux from mitochondrion, by mediating the exchange of 3 sodium ions per 1 calcium ion. 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. 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. Required for store-operated Ca(2+) entry (SOCE) and Ca(2+) release-activated Ca(2+) (CRAC) channel regulation: sodium transport by SLC8B1 leads to promote calcium-shuttling that modulates mitochondrial redox status, thereby regulating SOCE activity. Involved in B-lymphocyte chemotaxis. Able to transport Ca(2+) in exchange of either Li(+) or Na(+), explaining how Li(+) catalyzes Ca(2+) exchange. In contrast to other members of the family its function is independent of K(+).

Target Subcellular Location

Target Protein Families

Ca(2+):cation antiporter (CaCA) (TC 2.A.19) family, SLC24A subfamily
