Degradation of transmembrane proteins in Ca2+-enriched human erythrocytes. An immunochemical study.

Apart from causing the formation of gamma-glutamyl-epsilon-lysine cross-linked polymers, exposure of human erythrocytes to Ca2+ and ionophore A23187 leads to a breakdown of the two major transmembrane proteins, i.e. the anion-transporting band 3 and glycophorin. This apparently proteolytic phenomeno... View More
