产品介绍 : Plays a role in mediating 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.
Function:
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.
Subunit:
Forms homooligomers and heterooligomers with STIM2. Interacts with ORAI1. Interacts with MAPRE1; probably required for targeting to the growing microtubule plus ends. Interacts with EFCAB4B/CRACR2A; the interaction is direct and takes place in absence of Ca(2+). Forms a complex with EFCAB4B/CRACR2A and ORAI1 at low concentration of Ca(2+), the complex dissociates at elevated Ca(2+) concentrations. Interacts with TMEM66/SARAF, promoting a slow inactivation of STIM1-dependent SOCE activity, possibly by facilitating the deoligomerization of STIM1.
Subcellular Location:
Cell membrane. Endoplasmic reticulum membrane. Cytoplasm > cytoskeleton. Translocates from the endoplasmic reticulum to the cell membrane in response to a depletion of intracellular calcium. Associated with the microtubule network at the growing distal tip of microtubules.
Tissue Specificity:
Ubiquitously expressed in various human primary cells and tumor cell lines.
Post-translational modifications:
Glycosylation is required for cell surface expression.
Phosphorylated predominantly on Ser residues.
DISEASE:
Defects in STIM1 are the cause of immune dysfunction with T-cell inactivation due to calcium entry defect type 2 (IDTICED2) [MIM: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.
Similarity:
Contains 1 EF-hand domain.
Contains 1 SAM (sterile alpha motif) domain.
