Properties of human erythrocyte membrane proteins are widely studied recently. Comprehensive data were obtained on two main membrane proteins responsible for essential membrane functions. Besides, high performance two-dimensional electrophoresis and a number of other procedures enabled to detect more than 100 minor proteins in the biomembranes. The latest advances in studies of proteins and their coding genes allowed to compile a catalogue for erythrocyte membrane proteins, which is of importance for investigations in the field of membrane molecular biology. Structural organization of the catalogue for human erythrocyte membrane proteins is discussed.
