Calcium transport by red blood cell membranes from young and adult cattle

Short Communications Cellular and Molecular Biology, Immunology


It is shown using inside-out membrane vesicles that cattle red cells extrude calcium by means of a calmodulin sensitive Ca-pump whose activity is high in calves and extremely low in adult cows. The deline is not due to loss of calmodulin susceptibility nor to a drop in Ca-affinity.
