Phosphate ion channels in sarcoplasmic reticulum of rabbit skeletal muscle
1. Phosphate ions (Pi) enter intracellular Ca2+ stores and precipitate Ca2+. Since transport pathways for Pi across the membrane of intracellular calcium stores have not been identified and anion channels could provide such a pathway, we have examined the Pi conductance of single anion channels from the sarcoplasmic reticulum (SR) of rabbit skeletal muscle using the lipid bilayer technique. 2. Two anion channels in skeletal muscle SR, the small conductance (SCI) and big conductance (BCl)...[Show more]
