title: Cyclic nucleotide-regulated ion channels: spotlight on symmetry.
abstract: In this issue of Structure, Chiu et al. (2007) report the 16 A EM structure of the prokaryotic cyclic nucleotide-regulated K(+) channel MloK1. This structure reveals that the channel is arranged as a four-fold symmetric tetramer.
