  • Title: [Electroregulated potassium channels of the somatic membrane of mollusk neuron membranes].
    Author: Magura IS, Vikhreva LA.
    Journal: Neirofiziologiia; 1984; 16(3):296-307. PubMed ID: 6087167.
    Abstract:
    The delayed potassium current in mollusc neurons was separated into two components: a noninactivating component and a transient (inactivating) component. A noninactivating potassium current is not affected by changes in temperature, whereas an inactivating component decreases substantially under cooling. Internal Na+ can block the delayed outward potassium current. The blockade of the inactivating potassium current is strongly voltage-dependent. The voltage dependence of the blockade of the noninactivating potassium current is not so clear. These results are consistent with the hypothesis that there are two forms of the delayed potassium current channel. The effect of temperature and internal Na+ on the fast outward current is similar to that on the inactivating component of the delayed potassium current.
