Anti-ORAI-1

Anti-ORAI-1 antibody is directed against the human ORAI-1.  The product was prepared from monospecific antiserum by delipidation and defibrination. Cross-reactivity with ORAI1 from other sources have not been determined. Protein function: Ca(2+) release-activated Ca(2+) (CRAC) channel subunit which mediates Ca(2+) influx following depletion of intracellular Ca(2+) stores and channel activation by the Ca(2+) sensor, STIM1 (PubMed:16582901, PubMed:16645049, PubMed:16733527, PubMed:16766533, PubMed:16807233, PubMed:19249086, PubMed:23307288, PubMed:24351972, PubMed:24591628). CRAC channels are the main pathway for Ca(2+) influx in T-cells and promote the immune response to pathogens by activating the transcription factor NFAT (PubMed:16582901). [The UniProt Consortium]
