S100C (S100A11),OR CALGIZZARIN, IN COMPLEX WITH ANNEXIN I N-TERMINUS
Overview
Background: S100C (S100A11) is a member of the S100 calcium-binding, protein family, the function of which is not yet entirely clear, but may, include cytoskeleton assembly and dynamics. S100 proteins consist of two, EF-hand calcium-binding motifs, connected by a flexible loop. Like several, other members of the family, S100C forms a homodimer. A number of S100, proteins form complexes with annexins, another family of calcium-binding, proteins that also bind to phospholipids. Structural studies have been, undertaken to understand the basis of these interactions. Results: We have, solved the crystal structure of a complex of calcium-loaded S100C with a, synthetic peptide that corresponds to the first 14 residues of the annexin, I N terminus at 2.3 A resolution. We find a stoichiometry of ... [(full description)]
