Duffy Antigen System

Duffy Antigen System

Duffy antigen/chemokine receptor (DARC) also known as Fy glycoprotein (FY) or CD234 (Cluster of Differentiation 234) is a protein that in humans is encoded by the DARC gene.

The Duffy antigen is located on the surface of red blood cells, and is named after the patient in which it was discovered. The protein encoded by this gene is a glycosylated membrane protein and a non-specific receptor for several chemokines. The protein is also the receptor for the human malarial parasites Plasmodium vivax and Plasmodium knowlesi. Polymorphisms in this gene are the basis of the Duffy blood group system.

Famous quotes containing the word system:

    I need not say what match I would touch, what system endeavor to blow up; but as I love my life, I would side with the light, and let the dark earth roll from under me, calling my mother and my brother to follow.
    Henry David Thoreau (1817–1862)
