SINGLE-CHANNEL ION CURRENTS IN THE NUCLEAR ENVELOPE OF RAT CARDIOMYOCYTES
Abstract:
Using the patch clamp technique in nucleus attached configuration we have found that the nuclear membrane of rat cardiomyocytes contains different types of ion channels with conductances in the range from 10 to 400 pS. In particular, we recorded inositol 1,4,5-trisphosphate receptors with conductance of 384 ± 5 pS and 209 ± 13 pS cation channels similar to LCC-channels, previously reported in neurons. In addition, we found at least two types of ion channels with significantly higher conductance than that of LCC-channels and several types of ion channels with lower conductance (10-90 pS).

Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...
Voltage-gated Ion Channels
Generally, all voltage-gated ion channels have a 'voltage-sensing domain' that spans the lipid bilayer. The charged residues in the sensor move in response to the membrane potential changes that open the channel allowing ions movement. There are several types of...
