Phosphorylation of intact erythrocytes in human muscular dystrophy.

The uptake of exogenous 32Pi into the membrane proteins of intact erythrocytes was measured in 8 patients with Duchenne muscular dystrophy. No abnormalities were noted after autoradiographic analysis. This contrasts with earlier results obtained when isolated membranes were phosphorylated with gamma-[32P]ATP, and suggests a possible reinterpretation of those experiments.
