Calcium channel subtypes differentially regulate fusion pore stability and expansion
(2007)
Various studies have focused in the relative contribution of different voltage-activated Ca2+ channels (VACC) to total transmitter release. However, how Ca2+ entry through a given VACC subtype defines the pattern of ...

Bull, Ricardo, Juan Jose´ Marengo, Jose´ Pablo Finkelstein, Marı´a Isabel Behrens, and Osvaldo Alvarez. SH
oxidation coordinates subunits of rat brain ryanodine receptor channels activated by calcium and ATP. Am J ...
Clustering and coupled gating modulate the activity in KcsA, a potassium channel model
(AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, 2006-07-07)
Different patterns of channel activity have been detected by patch clamping excised membrane patches from reconstituted giant liposomes containing purified KcsA, a potassium channel from prokaryotes. The more frequent ...
Diverse calcium channel types are present in the human placental syncytiotrophoblast basal membrane
(W B SAUNDERS CO LTD, 2006-12)
The functional expression of calcium channels has been scarcely studied in human placental syncytiotrophoblast. We have presently sought to characterize Ca2+ currents of the healthy syncytiotrophoblast basal membrane using ...
A VLC Channel Model for Underground Mining Environments With Scattering and Shadowing
(IEEE-Inst Electrical Electronics Engineers, 2020)
Underground mining is an industry that preserves the miners' safety and efficiency in their work using wireless communication systems as a tool. In addition to communication links characterized by radio frequency signals, ...
Modulation of the Shaker K+ channel gating kinetics by the S3-S4 linker
(ROCKEFELLER UNIV PRESS, 2000-02)
In Shaker K+ channels depolarization displaces outwardly the positively charged residues of the S4 segment. The amount of this displacement is unknown, but large movements of the S4 segment should be con strained by the ...
Gating charge displacement in a monomeric voltage-gated proton (Hv1) channel
(National Academy of Sciences, 2018)
© 2018 National Academy of Sciences. All Rights Reserved. The voltage-gated proton (Hv1) channel, a voltage sensor and a conductive pore contained in one structural module, plays important roles in many physiological ...
Energy-efficient channel estimation
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
We investigate the energy-efficient channel estimation in wireless networks, where one pilot is inserted for every several data slots to estimate the channel coefficients. Both the channel state information estimation error ...
Localization of the K+ lock-in and the Ba2+ binding sites in a voltage-gated calcium-modulated channel: Implications for survival of K+ permeability
(The Rockefeller University, 1999)
Using Ba2
1 as a probe, we performed a detailed characterization of an external K
1 binding site located
in the pore of a large conductance Ca2
1-activated K
1 (BKCa) channel from skeletal muscle incorporated into
planar ...
Electrophysiological characterization of potassium conductive pathways in Trypanosoma cruzi
(2011)
Potassium channels (K+ channels) are members of one of the largest and most diverse families of membrane proteins, widely described from bacteria to humans. Their functions include voltage-membrane potential maintenance, ...
