Glutamic Acid 228-241 S100 calcium binding protein B Homo sapiens 51-54 23399701-10 2013 In addition, for the first time, to our knowledge, these data indicate that S100B secretion can be modulated by nicotinic receptors, in addition to glutamate, dopamine and serotonin receptors. Glutamic Acid 148-157 S100 calcium binding protein B Homo sapiens 76-81 22359053-0 2012 High-glucose and S100B stimulate glutamate uptake in C6 glioma cells. Glutamic Acid 33-42 S100 calcium binding protein B Homo sapiens 17-22 22359053-6 2012 Moreover, glutamate uptake in C6 glioma cells, like primary astrocytes, was stimulated by extracellular S100B. Glutamic Acid 10-19 S100 calcium binding protein B Homo sapiens 104-109 21886773-5 2011 METHODOLOGY/PRINCIPAL FINDINGS: Searching for possible TRAF binding sites on Nef, we found a TRAF2 consensus binding site in the AQEEEE sequence encompassing the conserved four-glutamate acidic cluster. Glutamic Acid 177-186 S100 calcium binding protein B Homo sapiens 77-80 19853332-6 2010 RESULTS: S-100B in the glutamate group and the control group were 0.079+/-0.034microg/L and 0.090+/-0.042microg/L respectively (p=0.245). Glutamic Acid 23-32 S100 calcium binding protein B Homo sapiens 9-15 28031466-7 2017 Mutagenesis of Nef amino acids Arg-134, Glu-174, and Asp-175, which stabilize Nef for AP-2 alpha-sigma2 binding in a recent co-crystal structure, substantially reduced AP-2 interaction without affecting CD4 binding. Glutamic Acid 40-43 S100 calcium binding protein B Homo sapiens 15-18 19469484-5 2009 The SBi279 binding site on Ca(2+)-S100B overlaps the SBi132 and SBi523 sites and contacts residues in both loop 2 (Ser-41, His-42, Phe-43, Leu-44, and Glu-45) and helix 4 (Ile-80, Ala-83, Cys-84, Phe-87, and Phe-88). Glutamic Acid 151-154 S100 calcium binding protein B Homo sapiens 34-39 15491611-7 2004 Molecular modeling identified three residues in the core region of SF2 Nef (Ala83, His116, and Tyr120) which are substituted in ELI with Glu, Asn, and Ile, respectively. Glutamic Acid 137-140 S100 calcium binding protein B Homo sapiens 71-74 16794859-0 2006 High glutamate decreases S100B secretion by a mechanism dependent on the glutamate transporter. Glutamic Acid 5-14 S100 calcium binding protein B Homo sapiens 25-30 16794859-2 2006 Extracellular S100B protects hippocampal neurons from excitotoxic damage, whilst toxic levels of glutamate to neurons have been shown to reduce S100B secretion in astrocytes and brain slices, by an unknown mechanism. Glutamic Acid 97-106 S100 calcium binding protein B Homo sapiens 144-149 16794859-4 2006 DCG-IV, an agonist of group II metabotropic glutamate receptors, caused a smaller decrease in S100B secretion when compared to 1 mM glutamate. Glutamic Acid 44-53 S100 calcium binding protein B Homo sapiens 94-99 16794859-5 2006 D: -aspartate partially reverted the glutamate effect on S100B release and two other inhibitors, PDC and DIDS, reverted it completely. Glutamic Acid 37-46 S100 calcium binding protein B Homo sapiens 57-62 16794859-6 2006 These findings suggest that S100B secretion is inversely coupled to glutamate uptake. Glutamic Acid 68-77 S100 calcium binding protein B Homo sapiens 28-33 12486136-7 2003 The leucine residues of the EXXXLL motif found in Nef were required for binding to AP-1 and AP-3 in vitro and for the stabilization of these complexes on membranes in vivo, whereas the glutamic acid residue of this motif was required specifically for the binding and stabilization of AP-3. Glutamic Acid 185-198 S100 calcium binding protein B Homo sapiens 50-53 34073816-6 2021 Intracellularly the S100B protein has a protective effect on neurons against the toxic effects of glutamate and stimulates neurites outgrowth and neuronal survival. Glutamic Acid 98-107 S100 calcium binding protein B Homo sapiens 20-25 26382833-12 2015 In addition, varying amounts of S100B caused inhibition of glutamate uptake in astroglia in a dose-dependent manner. Glutamic Acid 59-68 S100 calcium binding protein B Homo sapiens 32-37 26382833-14 2015 We speculate that S100B release by activated astroglia may have multiple roles in the pathophysiology of WNV neuro-invasive disease, including induction of neutrophil migration to the sites where blood brain barrier is disrupted as well as glutamate neurotoxicity. Glutamic Acid 240-249 S100 calcium binding protein B Homo sapiens 18-23 25122770-5 2014 A new intercomplex contact was found between SH3 Glu-93, and Nef Arg-105.
