The transferrin receptor of the parasite Trypanosoma brucei is a heterodimeric protein complex encoded by the 2 expression site-associated genes (ESAGs) 6 and 7. ESAG6 is a heterogeneously glycosylated protein of 50-60 kDa modified by a glycosylphosphatidylinositol anchor at the C-terminus, while ESAG7 is a 40-42 kDa glycoprotein carrying an unmodified C-terminus. In order to determine whether glycosylation is necessary for dimer formation and ligand binding, the receptor was expressed in...[Show more]
