STIM2, also named as KIAA1482, functions as a highly sensitive Ca2+ sensor in the endoplasmic reticulum which activates both store-operated and store-independent Ca2+-influx. Regulates basal cytosolic and endoplasmic reticulum Ca2+ concentrations. Upon mild variations of the endoplasmic reticulum Ca2+ concentration, STIM2 translocates from the endoplasmic reticulum to the plasma membrane where it probably activates the Ca2+ release-activated Ca2+ (CRAC) channels ORAI1, ORAI2 and ORAI3. STIM2 may inhibit STIM1-mediated Ca2+ influx. STIM2 has 2 isoforms 105kd and 115kd with Differential levels of phosphorylation.
Cholesterylation of Smoothened is a calcium-accelerated autoreaction involving an intramolecular ester intermediate.
Cell Mol Life Sci
STIM2 regulates NMDA receptor endocytosis that is induced by short-term NMDA receptor overactivation in cortical neurons
The calcium channel proteins ORAI3 and STIM1 mediate TGF-β induced Snai1 expression.
Inhibiting store-operated calcium entry attenuates white matter secondary degeneration following SCI.
STIM1 negatively regulates Ca2+ release from the sarcoplasmic reticulum in skeletal myotubes.
RGS10 physically and functionally interacts with STIM2 and requires store-operated calcium entry to regulate proinflammatory gene expression in microglia.
