This entry represents the C-terminal regulator of K+ conductance (RCK) domains which appear as tandem domains in these proteins [1-5]. The RCK domain has a Rossmann-fold topology with unique positions that compose a well-conserved salt bridge and a hydrophobic dimer interface. This domain is also presents in prokaryotic K+ channels.
