|Application ||WB, E|
|Other Accession||NP_116179, 84876, 109305 (mouse)|
|Calculated MW||32668 Da|
|Other Names||Calcium release-activated calcium channel protein 1, Protein orai-1, Transmembrane protein 142A, ORAI1, CRACM1, TMEM142A|
|Format||0.5 mg IgG/ml in Tris saline (20mM Tris pH7.3, 150mM NaCl), 0.02% sodium azide, with 0.5% bovine serum albumin|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||Goat Anti-ORAI1 / CRACM1 Antibody is for research use only and not for use in diagnostic or therapeutic procedures.|
|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).|
|Cellular Location||Cell membrane; Multi-pass membrane protein. Cytoplasmic vesicle, autophagosome. Note=Isoform beta is more mobile in the plasma membrane. Colocalizes with UBQLN1 in the autophagosome|
