Glycophorins
Glycophorins are integral membrane proteins in the cell membrane of erythrocytes . Glycophorins are the most common transmembrane proteins found in human erythrocytes. They are heavily glycolized and contribute (along with other glycoproteins and glycolipids ) to the negative charges on the surface of the erythrocyte membrane. By rejecting other negatively charged molecules, this charge prevents interactions with other blood components and endothelial cells . Glycophorins are on the adapter proteins ankyrin , band-4.1 protein , and actin with Spektrinfilamenten linked.
Glycophorins are used by the malaria pathogen Plasmodium falciparum to get into the erythrocytes.
Four glycophorins are known in humans:
- Glycophorin A
- Glycophorin B
- Glycophorin C
- Glycophorin E.
