靶點詳情

  • 功能：
    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.
  • 基因功能參考文獻：
    1. Expression of full-length STIM1 with STIM2 in a 5:1 ratio causes suppression of sustained agonist-induced Ca(2+) oscillations and protects cells from Ca(2+) overload. PMID: 29581306
    2. Stim2 deletion reduced SOCE by more than 90% in NIH 3T3 cells and abolishes STIM1 translocation to plasma membrane-associated ER membrane junctions. PMID: 29783744
    3. With STIM2 being essential for life, but apparently not for development, newly available data demonstrate a complex and still intriguing behaviour that this review summarizes, updating current knowledge of STIM2 function [review] PMID: 28087881
    4. The STIM2 protein play important roles in TGF-beta-induced EMT and these effects are related to both store-operated calcium entry and non-store-operated calcium entry. PMID: 28479254
    5. What is less clear is how the spatial and temporal spread of intracellular Ca(2+) is shaped and regulated by differential expression of the individual SOCE genes and their splice variants, their heteromeric combinations and pre- and posttranslational modifications. This review focuses on principle mechanisms regulating expression, splicing, and targeting of Ca(2+) release-activated Ca(2+) (CRAC) channels. PMID: 26911279
    6. While STIM1 is a full Orai1-agonist, leucine-replacement of this crucial residue in STIM2 endows it with partial agonist properties, which may be critical for limiting Orai1 activation stemming from its enhanced sensitivity to store-depletion PMID: 24492416
    7. These results imply that the splice variant STIM2.1 is an additional player tuning Orai1 activation in vivo. PMID: 25896806
    8. STIM2.1 cannot activate Orai1 due to splicing in residues within the channel-activating domain (CAD). STIM2.1 confers a calcium dependent dominant-negative function on both STIM1 and STIM2 (STIM2.2). Affinity of the STIM2.1 calmodulin binding site within the CAD domain is increased compared to STIM2.2. PMID: 25896806
    9. STIM2 enhances receptor-stimulated Ca(2) signaling by promoting recruitment of STIM1 to the endoplasmic reticulum-plasma membrane junctions. PMID: 25587190
    10. STIM2beta does not by itself strongly bind Orai1, it is recruited to Orai1 channels by forming heterodimers with other STIM isoforms. PMID: 26033257
    11. Imin channels are regulated by STIM2, TRPC3-containing INS channels are induced by STIM1, and TRPC1-composed Imax channels are activated by both STIM1 and STIM2. PMID: 25533457
    12. The higher amplitude of store-operated Ca2+ entry was associated to the over-expression for Stim2, Orai2-3, and TRPC1 while Stim2 levels remained constant and Stim1, Orai1, Orai3, TRPC1 and TRPC4 proteins were over-expressed in primary myelofibrosis. PMID: 24603752
    13. the reciprocal shift in transient receptor potential channel 1 (TRPC1) and stromal interaction molecule 2 (STIM2) contributes to Ca2+ remodeling and cancer hallmarks in colorectal carcinoma cells PMID: 25143380
    14. STIM2 is highly expressed and controls store-operated Ca(2+) entry in human melanoma. The invasive and migratory potential of melanoma cells was reduced upon silencing of STIM2. PMID: 24472175
    15. Binding of the lysine rich domains of STIM1 and STIM2 to phosphatidylinositol 4,5 biphosphate rich liposomes depends on their oligomerization. PMID: 24044355
    16. STIM2 is involved in spatial learning and plays an important role in ischemic-induced neuronal cell death during brain hypoxia. The absence of STIM2 reduces life expectancy in mice by sudden death. PMID: 198439
    17. STIM2 regulates store-operated Ca2+ entry as a sensor of mild reductions in ER calcium levels. PMID: 23359669
    18. The role of STIM2 in store operated calcium entry and its relevance in cellular physiology. [review] PMID: 22477146
    19. Studies indicate that in vertebrates, stromal interaction molecule proteins STIM1 and STIM2 are expressed ubiquitously PMID: 22914293
    20. It was shown that polyamines regulate intestinal epithelial restitution through TRPC1-mediated Ca2+ signaling by altering the ratio of STIM1 to STIM2. Overexpression of ornithine decarboxylase resulted in increased STIM1 but decreased STIM2 expression. PMID: 22592407
    21. Stromal interaction molecule 2 is frequently overexpressed in colorectal tumors and confers a tumor cell growth suppressor phenotype. PMID: 22125164
    22. Stim1 and Stim2 were increased in brains of chronic epileptic rodents and strongly expressed in hippocampal specimens from medial temporal lobe epilepsy patients. PMID: 21906591
    23. STIM1 and STIM2 are located in the acidic Ca2+ stores and associates with Orai1 upon depletion of the acidic stores in human platelets. PMID: 21321120
    24. a new model for STIM2-mediated regulation of ORAI1 in which two distinct proteins, STIM2 and preSTIM2, control store-dependent and store-independent modes of ORAI1 activation. PMID: 21383014
    25. Data suggest that divergent Ca(2+)- and SAM-dependent stabilization of the EF-SAM fold contributes to the disparate regulation of store-operated Ca(2+) entry by STIM1 and STIM2. PMID: 21217057
    26. involved in both store-operated calcium entry and cell proliferation PMID: 20172609
    27. STIM2 is a necessary partner of STIM1 for excitation-contraction coupling. PMID: 20436167
    28. STIM proteins function as Ca(2+) store sensors in the signaling pathway connecting Ca(2+) store depletion to Ca(2+) influx. PMID: 16005298
    29. STIM2 is an inhibitor of store-operated channel (SOC) activation and plays a coordinated role with STIM1 in controlling SOC-mediated Ca(2+) entry signals. PMID: 16860747
    30. STIM2 has two modes of activating CRAC channels: a store-operated mode activated through depletion of ER Ca2+ stores by inositol 1,4,5-trisphosphate and store-independent activation mediated by cell dialysis; both regulated by calmodulin. PMID: 17905723
    31. Study places STIM2 at the center of a feedback module that keeps basal cytosolic and endoplasmic reticulum Ca2+ concentrations within tight limits. PMID: 18160041
    32. Our biophysical studies reveal a structural stability difference in the EF-SAM region between STIM1 and STIM2, which may account for their different biological functions. PMID: 18166150
    33. distinct oligomerization dynamics of STIM isoforms have evolved to adapt to differential roles in Ca(2+) homeostasis and signaling PMID: 19019825
    34. Data demonstrate that cellular levels of STIM1 and STIM2, which are key players in capacitative Ca2+ entry, depend on presenilins. PMID: 19111578
    35. results provide evidence for a role of STIM1 protein in the control of Ca2+ influx in neutrophils excluding a STIM2 involvement in this process PMID: 19433064
    36. Results show that the 55-amino-acid STIM2 terminus substituted within STIM1 strikingly enhances both Orai1-mediated Ca(2+) entry and constitutive coupling to activate Orai1 channels. PMID: 19487696
