Physiol. Biochem. 51:1164-1178(2018). CC -!- FUNCTION: Cytosolic sensor for calcium, modulates the interaction CC of STIM1 and ORAI1 upon store depletion, the activation of store- CC operated Ca(2+) entry (SOCE) and NFAT translocation from cytosol CC to nucleus. {ECO:0000269|PubMed:30481768}. CC -!- SUBUNIT: Interacts with STIM1 and ORAI1; the interactions take CC place upon Ca(2+)-store depletion and dissociate through a Ca(2+)- CC dependent mechanism. Interaction with STIM1 inhibits STIM1 CC interaction with SARAF. {ECO:0000269|PubMed:30481768}. CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305|PubMed:30481768}.
