THE STRUCTURE OF CALCYCLIN REVEALS A NOVEL HOMODIMERIC FOLD FOR S100 CA2+-BINDING PROTEINS, NMR, 22 STRUCTURES
|
OverviewOverview
The S100 calcium-binding proteins are implicated as effectors in, calcium-mediated signal transduction pathways. The three-dimensional, structure of the S100 protein calcyclin has been determined in solution in, the apo state by NMR spectroscopy and a computational strategy that, incorporates a systematic docking protocol. This structure reveals a, symmetric homodimeric fold that is unique among calcium-binding proteins., Dimerization is mediated by hydrophobic contacts from several highly, conserved residues, which suggests that the dimer fold identified for, calcyclin will serve as a structural paradigm for the S100 subfamily of, calcium-binding proteins.
