功能：Plays a role in mediating store-operated Ca(2+) entry (SOCE), a Ca(2+) influx following depletion of intracellular Ca(2+) stores. Acts as Ca(2+) sensor in the endoplasmic reticulum via its EF-hand domain. Upon Ca(2+) depletion, translocates from the endoplasmic reticulum to the plasma membrane where it activates the Ca(2+) release-activated Ca(2+) (CRAC) channel subunit ORAI1. Involved in enamel formation. Activated following interaction with STIMATE, leading to promote STIM1 conformational switch.

- these data suggest that the loss of STIM1 and impaired store-operated calcium entry contribute to ER Ca(2+) dyshomeostasis under diabetic conditions PMID: 30131394
- deletion of the oncogenic KRAS allele resulted in enhanced STIM1 expression and greater Ca(2+) influx. PMID: 29748135
- Pore helix rotation by stromal interaction molecule 1 (STIM1) indicates the dynamic coupling between CRAC channel Orai1 gating and ion selectivity. PMID: 28220789
- the conserved portion of the Orai N terminus is essential for STIM1, as it fine-tunes the open Orai channel gating, thereby establishing authentic CRAC channel activity. PMID: 29237734
- The constitutive activation of Orai1 in Stormorken syndrome mainly involves the CRAC-activating domain CAD/SOAR of STIM1, the exposure of which is regulated by the molecular interplay between three cytosolic STIM1 coiled-coil (CC) domains. PMID: 29483506
- Each STIM1 protein monomer within the dimer interacts independently with single Orai1 subunits to mediate cross-linking between Orai1 channels. PMID: 29581306
- Results show that phosphorylation of STIM1 at Y361 is required to trigger store-operated Ca(2+) entry, and for STIM1-Orai1 interaction and recruitment of Orai1 to STIM1 puncta. Also, STIM1 phosphorylation at Y361 residue is required for increasing vascular permeability. PMID: 28218251
- The phosphorylation of the T389 residue in STIM1 is an essential feature determining the activity of store-independent ARC channels, and is mediated by an AKAP79/PKA-dependent process. PMID: 27847114
- An Orai1 C-terminal STIM1-binding site, situated far from the N-terminal pore helix, alone provides the trigger that is necessary and sufficient for channel gating. PMID: 27929067
- Stim1 silencing also reduced cell viability, caused cell apoptosis and cell cycle arrest in Multiple myeloma cell lines. PMID: 30114708

- Study provide clear evidence that STIM1 has a cholesterol-binding domain located inside the SOAR region and modulates Orai1 channels. A functional association of STIM1 and SOAR to cholesterol was shown, indicating a close proximity of SOAR to the inner layer of the plasma membrane. In contrast, the depletion of cholesterol induces the SOAR detachment from the plasma membrane and enhances its association to Orai1. PMID: 27459950

- Ca(2+) unbinding in the STIM1 luminal domains initiates the conformational change allowing SOAR domain liberation and clustering, leading to Orai1 channel activation. PMID: 28724757
- calmodulin (CaM) associates with the core region of STIM1 in a Ca2+-dependent manner. Consequently, calcium-bound CaM disrupts the STIM1-Orai1 complex and disassembles STIM1 oligomers, thereby inducing deactivation of the store-operated calcium entry. PMID: 29051492
