ORAI1, also known as Transmembrane protein 142A (TMEM142A), is a 32.7 kD multi-pass membrane protein belonging to the ORAI family.
Antigen stimulation of immune cells triggers Ca2+ entry through Ca2+ release-activated Ca2+ (CRAC) channels.
CRAC channels are the main pathway for Ca2+ influx in T-cells and promote the immune response to pathogens by activating the transcription factor NFAT.
ORAI1 is a four- transmembrane spanning protein that is an essential component of CRAC.
ORAI1 functions as a highly selective Ca2+ plasma membrane channel that is gated through interactions with STIM1, the store-activated endoplasmic reticulum Ca2+ sensor.
Defective ORAI1 in humans is the cause of one form of hereditary severe combined immune deficiency (SCID), which results in ablated T-cell Ca2+ entry.
