• The possible roles of K(+) channels in plant adaptation to high Na(+) conditions have not been extensively analyzed. Here, we… (More)

kappa-Conotoxin-PVIIA (kappa-PVIIA) is a 27-residue basic (+4) peptide from the venom of the predator snail Conus purpurascens. A… (More)

With prolonged stimulation, voltage-activated K+ channels close by a gating process called inactivation. This inactivation gating… (More)

At extreme membrane potentials, the unitary inward and outward currents through L-type Ca2+ channels become diffusion controlled… (More)

The diffusion of Ca as it converges to the external mouth of a Ca channel is examined. Diffusional limitation on Ca ions entering… (More)
