Orai1 / TRP channels

Name: Calcium release-activated calcium channel protein 1 (Orai1)
Official Symbol: ORAI1 provided by HGNC
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. 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.
