This statement is true. The **glycophorins** are major sialoglycoproteins of the red cell membrane. They are encoded by a gene family on chromosome 4. **GYPA** encodes glycophorin A (carries M/N antigens). **GYPB** encodes glycophorin B (carries S/s and U antigens). **GYPE** encodes glycophorin E (minor). **GYPC** encodes glycophorin C (and its splice variant glycophorin D), which carries the Gerbich blood group system antigens. These proteins contribute to membrane stability and carry multiple blood group antigens.
