STIM1 triggers a gating rearrangement at the extracellular mouth of the ORAI1 channel
The ER-resident regulatory protein STIM1 triggers store-operated Ca2+ entry by direct interaction with the plasma membrane Ca2+ channel ORAI1. The mechanism of channel gating remains undefined. Here we establish that STIM1 gates the purified recombinant ORAI1 channel in vitro, and use Tb3+ luminesce...
