Subunit Structure: Monomer in the presence of Ca2+; it oligomerizes in absence of Ca2+ (PubMed:18854159). Forms homooligomers and heterooligomers with STIM2 (PubMed:11463338, PubMed:11983428, PubMed:18854159, PubMed:22451904, PubMed:24351972, PubMed:24069340). Interacts (via the transmembrane region and the SOAR/CAD domain) with SPPL3; the interaction promotes the binding of STIM1 to ORAI1 (PubMed:25384971). Interacts with ORAI1 (PubMed:17905723, PubMed:19249086, PubMed:27185316, PubMed:24351972, PubMed:28219928). Interacts with MAPRE1; probably required for targeting to the growing microtubule plus ends (PubMed:19632184). Interacts with CRACR2A/EFCAB4B; the interaction is direct and takes place in absence of Ca2+ (PubMed:20418871). Forms a complex with CRACR2A/EFCAB4B and ORAI1 at low concentration of Ca2+, the complex dissociates at elevated Ca2+ concentrations (PubMed:20418871). Interacts with SARAF, promoting a slow inactivation of STIM1-dependent SOCE activity, possibly by facilitating the deoligomerization of STIM1 (PubMed:22464749). Interacts with ASPH (isoform 8) (PubMed:22586105). Interacts with SLC35G1; intracellular Ca2+-dependent. May interact with ATP1A1, ATP2A2, ATP2B1, ATP2B4, KPNB1 and XPO1; through SLC35G1 (PubMed:22084111). Interacts with TMEM203 (PubMed:25996873). Interacts with STIMATE, promoting STIM1 conformational switch (PubMed:26322679). Interacts with TMEM178A (By similarity). Interacts with CASQ1 (via C-terminal end and preferentially with the monomeric form); this interaction increases in response to a depletion of intracellular calcium, decreases both STIM1 aggregation and clustering, interaction of STIM1 with ORAI1 and store-operated Ca2+ entry (SOCE) activity (PubMed:27185316).
Post-translational Modifications: Glycosylation is required for cell surface expression. Phosphorylated predominantly on Ser residues.
Similarity: The microtubule tip localization signal (MtLS) motif; mediates interaction with MAPRE1 and targeting to the growing microtubule plus ends.The STIM1 Orai1-activating region/CRAC-activating domain (SOAR/CAD) mediates interaction with ORAI1 to activate the channel.
NCBI and Uniprot Product Information
Predicted: 78 kDa
NCBI Description
This gene encodes a type 1 transmembrane protein that mediates Ca2+ influx after depletion of intracellular Ca2+ stores by gating of store-operated Ca2+ influx channels (SOCs). It is one of several genes located in the imprinted gene domain of 11p15.5, an important tumor-suppressor gene region. Alterations in this region have been associated with the Beckwith-Wiedemann syndrome, Wilms tumor, rhabdomyosarcoma, adrenocrotical carcinoma, and lung, ovarian, and breast cancer. This gene may play a role in malignancies and disease that involve this region, as well as early hematopoiesis, by mediating attachment to stromal cells. Mutations in this gene are associated with fatal classic Kaposi sarcoma, immunodeficiency due to defects in store-operated calcium entry (SOCE) in fibroblasts, ectodermal dysplasia and tubular aggregate myopathy. This gene is oriented in a head-to-tail configuration with the ribonucleotide reductase 1 gene (RRM1), with the 3' end of this gene situated 1.6 kb from the 5' end of the RRM1 gene. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2013]
Uniprot Description
Plays a role in mediating store-operated Ca2+ entry (SOCE), a Ca2+ influx following depletion of intracellular Ca2+ stores (PubMed:15866891, PubMed:16005298, PubMed:16208375, PubMed:16537481, PubMed:16733527, PubMed:16766533, PubMed:16807233, PubMed:18854159, PubMed:19249086, PubMed:22464749, PubMed:24069340, PubMed:24351972, PubMed:24591628, PubMed:26322679, PubMed:25326555, PubMed:28219928). Acts as Ca2+ sensor in the endoplasmic reticulum via its EF-hand domain. Upon Ca2+ depletion, translocates from the endoplasmic reticulum to the plasma membrane where it activates the Ca2+ release-activated Ca2+ (CRAC) channel subunit ORAI1 (PubMed:16208375, PubMed:16537481). Involved in enamel formation (PubMed:24621671). Activated following interaction with STIMATE, leading to promote STIM1 conformational switch (PubMed:26322679).

Product Notes
The STIM1 stim1 (Catalog #AAA9608553) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The STIM1 Antibody reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's STIM1 can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), ELISA (EIA). WB: 1:1000-3000. Researchers should empirically determine the suitability of the STIM1 stim1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "STIM1, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
