## Abstract Isolated human erythrocyte membranes were exposed to a series of reagents known to modify or perturb proteins; these included sodium hydroxide, lithium diiodosalicylate, acid anhydrides, and organic mercurials. Each reagent liberated the same set of relatively polar polypeptides from th

## Abstract Treatment of isolated human erythrocyte membranes with Triton Xβ100 at ionic strength β0.04 preferentially released all the glycerolipid and glycoprotein species. At low ionic strength, certain nonglycosylated polypeptides were also selectively solubilized. The liberated polypeptides we
## Abstract Red blood cells contain a protein that activates membraneβbound (Ca^2+^ + Mg^2+^)βATPase and Ca^2+^ transport. The red blood cell activator protein is similar to a modulator protein that stimulates cyclic AMP phosphodiesterase. Wang and Desai [Journal of Biological Chemistry 252:4175β41
