GeneCards Summary for ORAI2 Gene
ORAI2 (ORAI Calcium Release-Activated Calcium Modulator 2) is a Protein Coding gene. Among its related pathways are Immune System and Downstream signaling events of B Cell Receptor (BCR). GO annotations related to this gene include store-operated calcium channel activity. An important paralog of this gene is ORAI3.
UniProtKB/Swiss-Prot for ORAI2 Gene
Ca(2+) release-activated Ca(2+)-like (CRAC-like) channel subunit which mediates Ca(2+) influx and increase in Ca(2+)-selective current by synergy with the Ca(2+) sensor, STIM1.
STIM-Orai channels have recently been identified as the underlying molecular mechanism of store-operated calcium entry (SOCE). STIM (stromal interaction molecule) proteins are ER Ca2+ sensors. Orai proteins are STIM binding partners that form the channel pore.
