Voltage-controlled gating in a large conductance Ca2+-sensitive K(+)channel (hslo)
(NATL ACAD SCIENCES, 1997-05-13)
Large conductance calcium- and voltage-sensitive K+ (MaxiK) channels share properties of voltage- and ligand-gated ion channels. In voltage-gated channels, membrane depolarization promotes the displacement of charged ...
Voltage-controlled gating in a large conductance Ca2+-sensitive K+ channel (hslo)
(National Academy of Sciences, 1997)
Large conductance calcium- and voltage-sensitive K+ (MaxiK) channels share properties of voltage-and ligand-gated ion channels. In voltage-gated channels, membrane depolarization promotes the displacement of charged residues ...
Molecular coupling between voltage sensor and pore opening in the Arabidopsis inward rectifier K+ channel KAT1
(ROCKEFELLER UNIV PRESS, 2003-10)
Animal and plant voltage-gated ion channels share a common architecture. They are made up of four subunits and the positive charges on helical S4 segments of the protein in animal K+ channels are the main voltage-sensing ...
Voltage-Gated K+/Na(+)Channels and Scorpion Venom Toxins in Cancer
(Frontiers Media, 2020)
Ion channels have recently been recognized as novel therapeutic targets in cancer research since they are overexpressed in different histological tissues, and their activity is linked to proliferation, tumor progression, ...
Outward rectification of voltage-gated k+ channels evolved at least twice in life history
(2015)
Voltage-gated potassium (K+) channels are present in all living systems. Despite high structural similarities in the transmembrane domains (TMD), this K+ channel type segregates into at least two main functional ...
Marine Toxins Targeting Ion Channels
(Molecular Diversity Preservation International, 2006-04)
This introductory minireview points out the importance of ion channels for cell communication. The basic concepts on the structure and function of ion channels triggered by membrane voltage changes, the so-called voltage-gated ...
Coupling of voltage-dependent gating and Ba++ block in the high-conductance, Ca++-activated K+ channel
(1987)
Voltage-dependent Ca++-activated K+ channels from rat skeletal muscle were reconstituted into planar lipid bilayers, and the kinetics of block of single channels by Ba++ were studied. The Ba++ association rate varies ...
S3b amino acid residues do not shuttle across the bilayer in voltage-dependent Shaker K+ channels
(2005)
In voltage-dependent channels, positive charges contained within the S4 domain are the voltage-sensing elements. The "voltage-sensor paddle" gating mechanism proposed for the KvAP K+ channel has been the subject of intense ...
