Disease relevance of S100b

 

High impact information on S100b

  • Here, we demonstrate that calcium-binding protein S100B, which is synthesized in considerable amounts in astrocytes (a major glial cell subtype), modulates long-term synaptic plasticity [4].
  • Characterization of the tumor suppressor protein p53 as a protein kinase C substrate and a S100b-binding protein [5].
  • Divergent pathways of gene expression are activated by the RAGE ligands S100b and AGE-BSA [6].
  • RESULTS: Treatment of human pancreatic islets with HG and S100b led to a three-five-fold induction of PTGS2 mRNA (p<0.001) [7].
  • We previously showed that, in contrast to the distribution of S100b (beta beta), S100a0 (alpha alpha) is mainly present in human skeletal and heart muscles at the level of 1-2 micrograms/mg of soluble protein and is universally distributed at high levels in skeletal and heart muscles of various mammals [8].
 

Biological context of S100b

  • The mouse Mif gene maps to the middle region of chromosome 10, between Bcr and S100b, which have been mapped to human chromosomes 22q11 and 21q22.3, respectively [9].
  • Cells expressing the pan-neuronal markers, neurofilament-M and Hu, or the glial marker, S100b, were observed undergoing mitosis [10].
 

Anatomical context of S100b

 

Associations of S100b with chemical compounds

  • Moreover, addition of citrate, a potent ligand for trivalent cations, resulted in a significant withdrawal in mAb recognition of aluminium which was previously bound to either CaM or S100b proteins [12].
 

Other interactions of S100b

  • These results suggest that a predominant form of S100 protein in human myocardial cells is not S100a (alpha beta) or S100b (beta beta), but S100a0 (alpha alpha) [13].
