General description
ORAI3 (ORAI calcium release-activated calcium modulator 3) is one of the three isoforms of the highly selective Ca2+ channel called ORAI. This isoform is exclusive to mammals. It contains an ORAI domain in its N-terminal, which is completely conserved. This protein, along with ORAI1, makes the arachidonate-regulated Ca2+ (ARC) channel, which is store-independent.
Immunogen
Protein orai-3 recombinant protein epitope signature tag (PrEST)
Application
Anti-ORAI3 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem/physiol Actions
ORAI3 (ORAI calcium release-activated calcium modulator 3) is a key member of the Ca2+ release-activated Ca2+ (CRAC) pathway, which is the predominant pathway to allow the entry of Ca2+ into the cell. This channel is activated when it either interacts with STIM1, or in the presence of 2-aminoethoxydiphenyl borate (2-APB). It is up-regulated in breast cancer cells, and in MCF-7 BC cell line it promotes cell cycle, cell growth and survival. It also regulates c-myc proto-oncogene, though the MAP kinase pathway. This channel is also controlled by estrogen receptor (ER)α, and in ERα+ breast cancer, it activates store-operated Ca2+ entry (SOCE), and facilitates tumorigenesis. In non-small cell lung adenocarcinoma, it might activate Akt pathway, which is responsible for cell proliferation and cell cycle progression.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.

Orai channels have been associated with cell proliferation, survival and metastasis in several cancers. The present study investigates the expression and the role of Orai3 in cell proliferation in non-small cell lung cancer (NSCLC). We show that Orai3 is over-expressed

Members of the Orai family are highly selective calcium ion channels that play an important role in store-operated calcium entry. Among the three known Orai isoforms, Orai3 has gained increased attention, notably for its emerging role in cancer. We recently

Store-operated Ca(2+) entry (SOCE) encoded by Orai1 proteins is a ubiquitous Ca(2+)-selective conductance involved in cellular proliferation and migration. We recently described up-regulation of Orai3 channels that selectively mediate SOCE in estrogen receptor α-expressing (ERα(+)) breast cancer cells. However, the
