ORAI Channel-Mediated Ca2+ Signals in Vascular and Airway Smooth Muscle.
United States. In Am J Physiol Cell Physiol, Jan 2016
UNASSIGNED: Orai proteins (Orai1-3) form a family of highly Ca(2+) selective plasma membrane channels that are regulated by stromal interacting molecules (STIM1 and STIM2); STIM proteins are Ca(2+) sensors located in the membrane of the endoplasmic reticulum (ER).
STIMATE reveals a STIM1 transitional state.

Decreases in endoplasmic reticulum calcium content are sensed by resident STIM proteins, which can activate plasma membrane Orai channels to facilitate Ca(2+) entry.
STIM proteins: dynamic calcium signal transducers.

Studies indicate that in vertebrates, stromal interaction molecule proteins STIM1 and STIM2 are expressed ubiquitously throughout cell types.
