== Function == | |||
[https://www.uniprot.org/uniprot/STIM2_HUMAN STIM2_HUMAN] Plays a role in mediating store-operated Ca(2+) entry (SOCE), a Ca(2+) influx following depletion of intracellular Ca(2+) stores. Functions as a highly sensitive Ca(2+) sensor in the endoplasmic reticulum which activates both store-operated and store-independent Ca(2+)-influx. Regulates basal cytosolic and endoplasmic reticulum Ca(2+) concentrations. Upon mild variations of the endoplasmic reticulum Ca(2+) concentration, translocates from the endoplasmic reticulum to the plasma membrane where it probably activates the Ca(2+) release-activated Ca(2+) (CRAC) channels ORAI1, ORAI2 and ORAI3. May inhibit STIM1-mediated Ca(2+) influx.<ref>PMID:16005298</ref> <ref>PMID:16860747</ref> <ref>PMID:17905723</ref> <ref>PMID:18160041</ref> <ref>PMID:21217057</ref> <ref>PMID:22464749</ref> <ref>PMID:23359669</ref> | |||
