Glycophorins

Glycophorins are integral erythrocyte cell membrane proteins, which apparently serve a variety of functions. Each of the glycophorin proteins has an external carbohydrate-carrying domain, and the surface carbohydrates may be involved in cell recognition. There is also evidence that glycophorin C interacts with the peripheral protein 4.1 via its intracellular domain.
