RESUMO
The effect of purified calmodulin on the calcium-dependent phosphorylation of human erythrocyte membranes was studied. Under the conditions employed, only one major peak of phosphorylation was observed when solubilized membrane proteins were analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The molecular weight of this phosphorylated protein band was estimated to be 130000 and in the presence of purified red blood cell calmodulin, the rate of phosphorylation of this band was increased. These data suggest that calmodulin activation of (Ca2+ + Mg2+)-ATPase could be a partial reflection of an increased rate of phosphorylation of the (Ca2+ + Mg2+)-ATPase of human erythrocyte membranes.
