Description

LP14537-2   F little y super little b
The Duffy glycoprotein is a receptor that binds cytokines released during inflammation. It also binds the malaria parasite Plasmodium vivax, and RBCs that lack the Duffy Fy^a and Fy^b antigens are resistant to invasion. Structurally, the Duffy protein is similar to the family of G-protein coupled receptors, having 7 transmembrane domains FY has two major codominant alleles, FYA and FYB, which result from a SNP (125G→A), and the corresponding Fy^a and Fy^b antigens differ by a single amino acid (G42D). Individuals who are homozygous for a -33T→C SNP in the erythroid promoter region of the FYB allele have the phenotype Fy(a-b-) and do not express Duffy antigens on their RBCs.
