In voltage-gated K(+) channels (Kv), membrane depolarization promotes a structural reorganization of each of the four voltage sensor domains surrounding the conducting pore, inducing its opening. Although the crystal structure of Kv1.2 provided the first atomic resolution view of a eukaryotic Kv channel, several components of the voltage sensors remain(More)
Ionotropic glutamate receptors (iGluRs) transduce the chemical signal of neurotransmitter release into membrane depolarization at excitatory synapses in the brain. The opening of the transmembrane ion channel of these ligand-gated receptors is driven by conformational transitions that are induced by the association of glutamate molecules to the(More)
Natural killer T (NKT) cells have recently been implicated in atherogenesis, primarily for their ability to recognize and respond to lipid antigens. Because the atherosclerotic lesion is characterized by the retention and modification of lipids in the vascular wall, NKT cells may be involved in promoting the local vascular inflammatory response. Here, we(More)
Voltage-dependent K + (Kv) channels are formed by the assembly of four protein subunits encompassing a central aqueous pore allowing for selective K + permeation across the lipid membrane. Each subunit is composed of six transmembrane segments (S1 – S6), the fi rst four segments (S1 – S4) constitute the voltage sensor domain, while the last two segments (S5(More)
The selectivity filter is an essential functional element of K(+) channels that is highly conserved both in terms of its primary sequence and its three-dimensional structure. Here, we investigate the properties of an ion channel from the Gram-positive bacterium Tsukamurella paurometabola with a selectivity filter formed by an uncommon proline-rich sequence.(More)
