Calbindin-D28k is known to function as a calcium-buffering protein in the cell. Moreover, recent evidence shows that it also plays a role as a sensor. Using circular dichroism and NMR, we show that calbindin-D28k undergoes significant conformational changes upon binding calcium, whereas only minor changes occur when binding target peptides in its Ca(2+)-loaded state. NMR experiments also identify residues that undergo chemical shift changes as a result of peptide binding. The subsequent use of computational protein-protein docking protocols produce a model describing the interaction interface between calbindin-D28k and its target peptides.
