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.
