• PubMed Abstract: 
  

S100B (S100beta) is a member of the S100 family of small calcium-binding proteins: members of this family contain two helix-loop-helix calcium-binding motifs and interact with a wide range of proteins involved mainly in the cytoskeleton and cell proliferation. S100B is a neurite-extension factor and levels of S100B are elevated in the brains of patients with Alzheimer's disease or Down's syndrome: the pattern of S100B overexpression in Alzheimer's disease correlates with the pattern of neuritic-plaque formation. Identification of a growing class of S100 proteins and the likely neurochemical importance of S100B make the determination of the structure of S100B of interest.
