We are deeply saddened by the passing of Amos Bairoch (1957–2025), the creator of PROSITE. We wish to dedicate our latest paper, published shortly before his death, to him. He will always be a source of inspiration to us.
Our deepest condolences go out to his family and friends, and to all those who had the privilege of working with him. Rest in peace, Amos. Your work will live on long after you are gone.
Amos Bairoch

Description

Glycophorin A is the major sialoglycoprotein of erythrocyte membrane [1]. Structurally, glycophorin A consists of an N-terminal extracellular domain, heavily glycosylated on serine and threonine residues, followed by a transmembrane region and a C-terminal cytoplasmic domain.

In human there are two closely related forms: glycophorin A which carries the blood group M/N antigen, and glycophorin B which carries the blood group S/s antigen.

The best conserved region of glycophorin A is the transmembrane domain and we have derived a consensus pattern from that region.
