Ca2+ influx is essential for a variety of cellular functions, such as secretion and transcription. Stim1 (stromal interaction molecule 1) is a ubiquitously expressed cell surface transmembrane glycoprotein that plays a role in mediating Ca2+ influx following the depletion of intracellular Ca2+ stores. Stim1 functions in the endoplasmic reticulum (ER) where it acts as a Ca2+ sensor via its EF-hand domain and is capable of causing large conformational changes in response to varying Ca2+ levels. When Ca2+ levels drop, Stim1 translocates from the ER to the plasma membrane, where it activates the Ca2+ release-activated Ca2+ (CRAC) channel subunit, Orai1. Stim2 (stromal interaction molecule 2) is a 746 amino acid protein that contains one EF-hand domain and one SAM domain and localizes to the ER as a single-pass type I membrane protein. Stim2 exists as an oligomer with Stim1 and plays an essential role in the inhibition of Stim1-mediated Ca2+ influx.
