Abstract

The endoplasmic reticulum (ER) Ca sensor stromal interaction molecule 1 (STIM1) interacts with ORAI Ca channels at the plasma membrane to regulate immune and muscle cell function. The conformational changes underlying STIM1 activation, translocation, and ORAI1 trapping and gating, are stringently regulated by post-translational modifications and accessory proteins. Here, we review the recent progress in the identification and characterization of ER and cytosolic proteins interacting with STIM1 to control its activation and deactivation during store-operated Ca entry (SOCE).
