[3H]taurine binding on a cardiac sarcoplasmic fraction from rats, rabbits and pigs.
A subcellular fraction was isolated from heart ventricles by differential centrifugation. Enzyme markers and electron microscopy showed that this fraction was rich in sarcoplasmic reticulum. It bound [3H]taurine specifically. Taurine might contribute to the regulation of Ca2+ transfer in the sarcoplasmic reticulum.
