External copper inhibits the activity of the large-conductance calcium- and voltage-sensitive potassium channel from skeletal muscle
(2003)
We have characterized the effect of external
copper on the gating properties of the large-conductance calcium- and voltage-sensitive potassium channel from skeletal muscle, incorporated into artificial
bilayers. The ...
Single Ca2+-activated Cl- channel currents recorded from toad olfactory cilia
(Biomed Central, 2016)
Background: Odor transduction, occurring in the chemosensory cilia of vertebrate olfactory sensory neurons, is triggered by guanosine triphosphate-coupled odor receptors and mediated by a cyclic adenosine monophosphate ...
Actin modifies Ca2+ block of epithelial Na+ channels in planar lipid bilayers
(BIOPHYSICAL SOCIETY, 2001-05)
The mechanism by which the cytoskeletal protein actin affects the conductance of amiloride-sensitive epithelial sodium channels (ENaC) was studied in planar lipid bilayers. In the presence of monomeric actin, we found a ...
Distributed structures underlie gating differences between the K in Channel KAT1 and the K out Channel SKOR
(Elsevier, 2010-01)
The family of voltage-gated (Shaker-like) potassium channels in plants includes both inward-rectifying (Kin) channels that allow plant cells to accumulate K+ and outward-rectifying (Kout) channels that mediate K+ efflux. ...
Identification of a sphingosine-sensitive Ca2+ channel in the plasma membrane of Leishmania mexicana
(Biochemical and Biophysical Research Communications, 2013)
Annexin 6 modulates the maxi-chloride channel of the apical membrane of syncytiotrophoblast isolated from human placenta
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2004-11-26)
The syncytiotrophoblast separates the maternal and fetal blood and constitutes the primary barrier for maternal-fetal transport. The Maxi-chloride channel from the apical membrane of the syncytiotrophoblast plays a role ...
Cilium-attached and excised patch-clamp recordings of odourant-activated Ca-dependent K channels from chemosensory cilia of olfactory receptor neurons
(2004)
It has previously been proposed that a Ca2+-dependent K + conductance is implicated in the inhibitory odourant response in rat and toad olfactory receptor neurons. Previous whole-cell and single-channel measurements on ...
Periodic perturbations in Shaker K+ channel gating kinetics by deletions in the S3-S4 linker
(NATL ACAD SCIENCES, 2001-08-14)
Upon depolarization positive charges contained in the transmembrane segment S4 of voltage-dependent channels are displaced from the cytoplasmic to the external milieu, This charge movement leads to channel opening. In ...
Temporal and spatial adjustments of channel migration and planform geometry: responses to ENSO driven climate anomalies on the tropical freely-meandering Aguapeí River, São Paulo, Brazil
(2018-06-30)
Two reaches of Aguapeí River, a left-bank tributary of the Paraná River in western São Paulo state, Brazil, were studied with the objective of assessing the role of bend curvature on channel migration in this wet-tropical ...
