The protein–domain–residue hierarchy. Two bound proteins and their interacting domains and residues, captured in PDB complex 4IOP. The proteins are a Killer cell lectin-like receptor (in violet) and its partner, a C-type lectin domain protein (in blue). (Left) Interaction as visible from the contact surface. (Center) The two C-type lectin domains instantiating the interaction. (Right) Effectively interacting residues in red.
