We determined the crystal structure of CNB-L at 2.0 A resolution in the absence of its C-terminal helix and nucleotide. The 3D structure of CNB-L is in a two-fold symmetric form. Each protomer shows high structure similarity to that of cGMP-binding domain-containing proteins, and likely mimics their nucleotide-free conformation. A key residue, Glu17, mediates the dimerization and prevents binding of cNMP to the canonical ligand-pocket. The structurally observed dimer of CNB-L is stable in solution, and thus is likely to be biologically relevant.
