== Disease == | |||
[https://www.uniprot.org/uniprot/STIM1_HUMAN STIM1_HUMAN] Defects in STIM1 are the cause of immune dysfunction with T-cell inactivation due to calcium entry defect type 2 (IDTICED2) [MIM:[https://omim.org/entry/612783 612783]. IDTICED2 is an immune disorder characterized by recurrent infections, impaired T-cell activation and proliferative response, decreased T-cell production of cytokines, lymphadenopathy, and normal lymphocytes counts and serum immunoglobulin levels. Additional features include thrombocytopenia, autoimmune hemolytic anemia, non-progressive myopathy, partial iris hypoplasia, hepatosplenomegaly and defective enamel dentition.<ref>PMID:19420366</ref> | |||
== Function == | |||
[https://www.uniprot.org/uniprot/STIM1_HUMAN STIM1_HUMAN] 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, TMEM142A/ORAI1.<ref>PMID:9377559</ref> <ref>PMID:16005298</ref> <ref>PMID:15866891</ref> <ref>PMID:16208375</ref> <ref>PMID:16807233</ref> <ref>PMID:16766533</ref> <ref>PMID:16733527</ref> <ref>PMID:16537481</ref> <ref>PMID:22464749</ref> | |||
