Please read the nature paper by Cheetham et al., 1998 doi:10.1038/2302, wher they compare the nmr str with its receptor bound conformation. Also you can read Krzyzanski's paper of 2007 doi: 10.1007/s11095-006-9195-y

Erythropoietin is a glycoprotein molecule composed of 165 amino acids and four carbohydrate groups. Two disulfide bonds tether the molecule together between cysteines 29 and 33 and cysteines 6 and 161. Three N-linked sugars are present at asparagines 24, 38, and 83, and one O-linked sugar is present at serine 126.
