PubMed Abstract: S100B, a small acidic calcium-binding protein, is a member of the S100 protein family and is a multifunctional protein capable of binding several target molecules, such as cytoskeletal proteins and protein kinases, in a calcium-dependent manner. S100B is a homodimer of S100 beta subunits (beta beta) with a total of four calcium-binding motifs called EF hands. S100B is found abundantly in nervous tissue and has been implicated in Alzheimer's disease and Down's syndrome. Structural analysis of S100B in the calcium-bound state is required to gain a better understanding of the conformational changes that occur to S100B upon calcium binding and to elucidate the mode of recognition between S100B and its target molecules.
