Small‐Conductance Calcium‐Activated Potassium Current in Normal Rabbit Cardiac Purkinje Cells
BackgroundPurkinje cells (PCs) are important in cardiac arrhythmogenesis. Whether small‐conductance calcium‐activated potassium (SK) channels are present in PCs remains unclear. We tested the hypotheses that subtype 2 SK (SK2) channel proteins and apamin‐

Identification of TREK channels in mouse intracardiac ganglion neurons
Abstract figure legend Role of TWIK‐related K+ (TREK) channels in intracardiac ganglion neurons. CD‐1 mice were used to establish primary cultures of intracardiac neurons for immunochemical characterization and patch‐clamp electrophysiology. Intracardiac neurons express functional TREK channels, which modulate neuronal excitability by regulating ...

The relationship between apamin binding and channel block in KCa2 potassium channels. [PDF]
Small conductance calcium-activated potassium channels (KCa2.1,2.2,2.3) are widely distributed throughout the body and are involved in diverse physiological processes including the regulation of neuronal firing and smooth muscle contraction.

Apamin, a highly specific Ca2+ blocking agent in heart muscle
Apamin, a bee venom polypeptide, was recently reported to block specifically the Ca2+-dependent K+ channels that are not blocked by tetraethylammonium chloride in muscle cells.

The pharmacology of hSK1 Ca2+-activated K+ channels expressed in mammalian cell lines. [PDF]
The pharmacology of hSK1, a small conductance calcium-activated potassium channel, was studied in mammalian cell lines (HEK293 and COS-7). In these cell types, hSK1 forms an apamin-sensitive channel with an IC(50) for apamin of 8 nM in HEK293 cells and ...
