C-type inactivation underlies important roles played by voltage-gated K+ (Kv) channels. Functional studies have provided strong evidence that a common underlying cause of this type of inactivation is an alteration near the extracellular end of the ch

Regulator of conductance of K+ (RCK) domains govern K+ channel and transporter activity through binding of cytosolic nucleotides or ions, although the locations and ligand-selectivities of activation sites within these domains can vary. To gain furth

MthK is a Ca(2+)-gated K(+) channel whose activity is inhibited by cytoplasmic H(+). To determine possible mechanisms underlying the channel's proton sensitivity and the relation between H(+) inhibition and Ca(2+)-dependent gating, we recorded curren

KcsA, a potassium channel from Streptomyces lividans, was the first ion channel to have its transmembrane domain structure determined by crystallography. Previously we have shown that its C-terminal cytoplasmic domain is crucial for the thermostabili

The prokaryotic potassium channel from Streptomyces lividans, KcsA, is the first channel that has a known crystal structure of the transmembrane domain. The crystal structure of its soluble C-terminal domain, however, still remains elusive. Biophysic

Ligand binding sites within proteins can interact by allosteric mechanisms to modulate binding affinities and control protein function. Here we present crystal structures of the regulator of K+ conductance (RCK) domain from a K+ channel, MthK, which

Regulator of K + conductance (RCK) domains control the activity of a variety of K + transporters and channels, including the human large conductance Ca 2+ -activated K + channel that is important for blood pressure regulation and control of neuronal

KcsA, a potassium channel from Streptomyces lividans, is a good model for probing the general working mechanism of potassium channels. To date, the physiological activator of KcsA is still unknown, but in vitro studies showed that it could be opened

MthK is a Ca2+-gated K+ channel whose activity is modulated by cytoplasmic pH. To determine possible mechanisms underlying the channel's pH sensitivity, we recorded current through MthK channels, which were purified from E.coli membranes, reconstitut

Summary RCK domains control activity of a variety of K + channels and transporters through binding of cytoplasmic ligands. To gain insight toward mechanisms of RCK domain activation, we solved the structure of the RCK domain from the Ca 2+ -gated K +
