Human STIM1 Protein expressed in Wheat germ - ABIN1321631
Hawkins, Irrinki, Mallilankaraman, Lien, Wang, Bhanumathy, Subbiah, Ritchie, Soboloff, Baba, Kurosaki, Joseph, Gill, Madesh: S-glutathionylation activates STIM1 and alters mitochondrial homeostasis. in The Journal of cell biology 2010
Downregulation of STIM1 levels in oocytes by siRNA completely inhibited the repetitive Ca(2 (show CA2 Proteins)+) signal triggered by the fertilizing sperm.
findings suggest that in oocytes, STIM1 serves as a sensor of Ca(2 (show CA2 Proteins)+) store content that after store depletion moves to the plasma membrane to stimulate store-operated Ca(2 (show CA2 Proteins)+) entry
STIM1 plays role in PAR1 (show F2R Proteins)-mediated Ca2 (show CA2 Proteins)+ influx and Ca2 (show CA2 Proteins)+-dependent NO production in endothelial cells; DNA sequence alignment of porcine and human STIM1
STIM1 is localized to the cleavage furrow during cytokinesis of the first and second cell division cycles in zebrafish embryos.
STIM1/TRPC1 (show TRPC1 Proteins)-dependent store-operated Ca2 (show CA2 Proteins)+ entry plays an essential role in generating spatiotemporal Ca2 (show CA2 Proteins)+ signals that mediate guidance responses of nerve growth cones.
STIM1 and Orai1 are essential components of the signal transduction cascade that regulates sex pheromone production.
STIM1 is significantly upregulated in GC and that STIM1 overexpression is associated with a poor prognosis in GC patients with LNM and an advanced TNM (show ODZ1 Proteins) stage. Therefore, STIM1 may be a useful prognostic marker for GC.
Here, we summarize the recent discoveries on the structure-function relationship of Orai1, as well as its interaction with the native channel opener STIM1 and chemical modulator 2-aminoethoxydiphenyl borate
the elevated expression of STIM1 might be involved in lung tumorigenesis.
TRPC1-STIM1 activation modulates transforming growth factor beta-induced epithelial-to-mesenchymal transition and cell migration.
Data show that the G98S and V107M mutations generate constitutively permeable ORAI1 channels, whereas T184M alters the channel permeability only in the presence of STIM1.
STIM1 contributes to the development of OTSCC.
Our findings demonstrate for the first time that STIM1 and store-operated calcium entry signaling are involved in the TGF-beta (show TGFB1 Proteins)-induced suppression of cell proliferation
Cultured hippocampal neurons expressing mutant PS1 (show PSEN1 Proteins) had attenuated CCE that was associated with destabilized dendritic spines, which were rescued by either gamma-secretase inhibition or overexpression of STIM1.
These findings suggest that the surface location of SARAF (show TMEM66 Proteins) is dependent on the expression of STIM1 in the plasma membrane.
sp(2) -Iminosugar alpha-glucosidase (show AGLU Proteins) inhibitor 1 (show PPP1R1A Proteins)-C-octyl-2-oxa-3-oxocastanospermine inhibits breast cancer cell migration via beta1-integrin, Stim1, and FAK (show PTK2 Proteins) signaling pathways.
STIM1 and STIM2 (show Stim2 Proteins) are expressed in bovine aortic endothelial cells and they both interact with IP3R-1 (show ITPR1 Proteins).
Stim1 and Stim2 (show Stim2 Proteins) deficient B cells show an accelerated pace of affinity maturation but do not have dramatically impaired antibody production to T-independent antigen immunization
STIM1 deletion protects the liver from ischemia/reperfusion injury in mice through inhibiting inflammation, oxidative stress and apoptosis.
These results highlight how STIM1-dependent Ca(2 (show CA2 Proteins)+) microdomains have a major impact on intracellular Ca(2 (show CA2 Proteins)+) homeostasis, cytoskeletal remodeling and cellular signaling, even when excitation-contraction coupling is present.
hearts of STIM1 haploinsufficient mice had a superficial resemblance to the WT phenotype under stress-free conditions; however, STIM1 haploinsufficient mice showed a maladaptive response to cardiac pressure overload
Loss-of-function mutations in the Ca(2 (show CA2 Proteins)+) release-activated Ca(2 (show CA2 Proteins)+) channel genes ORAI1 (show TMEM132A Proteins) and STIM1 abolish store-operated Ca(2 (show CA2 Proteins)+) entry (SOCE) and result in ectodermal dysplasia with amelogenesis imperfecta. SOCE is essential for proper enamel mineralization, in which Stim1 plays a critical role during the maturation process.
Reactive oxygen species (ROS (show ROS1 Proteins)) production, degranulation, and phagocytosis are normal in the absence of STIM2 (show Stim2 Proteins), suggesting STIM1 is the dominant calcium sensor required for classical short-term neutrophil responses
Stromal interaction molecule 1 (STIM1), which regulates the refilling of ER Ca(2 (show CA2 Proteins)+), has been investigated in several systems including the CNS. In addition to a previous study showing that STIM1 regulates dendritic ER Ca(2 (show CA2 Proteins)+) refilling and mGluR1 (show GRM1 Proteins)-mediated synaptic transmission, we provide compelling evidence describing a novel role of STIM1 in spike firing Purkinje neurons.
data indicate that STIM1 overexpression in neurons in the brain perturbs metabotropic glutamate (show GRIN1 Proteins) receptor signaling, leading to impairments in long-term depression and alterations in animal behavior
Ca(2 (show CA2 Proteins)+) entry serves critical cellular functions in virtually every cell type, and appropriate regulation of Ca(2 (show CA2 Proteins)+) in neurons is essential for proper function.
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. 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.
