This type of channel is the primary way for calcium influx into T-cells. Defects in this gene are a cause of immune dysfunction with T-cell inactivation due to calcium entry defect type 1 (IDTICED1). [provided by RefSeq, Sep 2011]. * **UniProt Summary**: 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, PubMed:28219928). 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). {ECO:0000269|PubMed:16582901, ECO:0000269|PubMed:16645049, ECO:0000269|PubMed:16733527, ECO:0000269|PubMed:16766533, ECO:0000269|PubMed:16807233, ECO:0000269|PubMed:19249086, ECO:0000269|PubMed:23307288, ECO:0000269|PubMed:24351972, ECO:0000269|PubMed:24591628, ECO:0000269|PubMed:28219928}. |Orai-1| |store-operated calcium entry| |positive regulation of adenylate cyclase activity| |store-operated calcium channel activity| |positive regulation of cyclase activity| |positive regulation of lyase activity| |regulation of adenylate cyclase activity| |plasma membrane raft| |calcium ion import| |regulation of cyclase activity| |regulation of lyase activity| |mammary gland epithelium development| |positive regulation of calcium ion transport| |mammary gland development| |basolateral plasma membrane| |calcium ion transmembrane transport| |calmodulin binding| |membrane raft| |regulation of calcium ion transport| |calcium ion transport| |positive regulation of ion transport| |divalent metal ion transport| |divalent inorganic cation transport| |regulation of metal ion transport| |gland development| |inorganic cation transmembrane transport| |protein-containing complex| |adaptive immune response| |cation transmembrane transport| |metal ion transport| |inorganic ion transmembrane transport| |regulation of ion transport| |cation transport| |ion transmembrane transport| |positive regulation of transport| |identical protein binding| |epithelium development| |transmembrane transport| |ion transport| |integral component of plasma membrane| |positive regulation of catalytic activity| |tissue development| |positive regulation of molecular function| |regulation of transport| |immune response| |membrane| \\ === CRISPR Data === No hits were found. ^Gene^Correlation^ |[[:human genes:h:hgc6.3|HGC6.3]]|0.587| Global Fraction of Cell Lines Where Essential: N/A ^Tissue^Fraction Of Cell Lines Where Essential^ == Essentiality in NALM6 == * **Essentiality Rank**: 15720 * **Expression level (log2 read counts)**: 3.78 {{:chemogenomics:nalm6 dist.png?nolink |}}
