  • Title: Potassium concentration influences the gating of K+ channels from sarcoplasmic reticulum.
    Author: Campos-de-Carvalho AC.
    Journal: Braz J Med Biol Res; 1989; 22(1):107-9. PubMed ID: 2758164.
    Abstract:
    Gating of K+ channels from the sarcoplasmic reticulum (SR) is influenced by the K+ concentration in the bathing solution. The probability of finding the channel open (Po) increases nonlinearly with the K+ concentration. The current two-state model which considers only voltage-dependent rate constants for the SR K+ channel should be reconsidered in the light of the present results.
