Glycosylation
Thy-1 is one of the most heavily glycosylated membrane proteins with a carbohydrate content up to 30% of its molecular mass. The composition of Thy-1 carbohydrate moieties varies considerably between different tissues or even among cells of the same lineage at different stages of differentiation: e.g., galactosamine only in brain Thy-1, sialic acid in thymic Thy-1 in far excess than brain Thy-1, that too increasing in parallel with T cell maturation
