Hypoxia-induced Acidosis Uncouples the STIM-Orai Calcium Signaling Complex
The endoplasmic reticulum Ca(2+)-sensing STIM proteins mediate Ca(2+) entry signals by coupling to activate plasma membrane Orai channels. We reveal that STIM-Orai coupling is rapidly blocked by hypoxia and the ensuing decrease in cytosolic pH. In smooth muscle cells or HEK293 cells coexpressing STI...
