3.4.21.120 glycoprotein contains terminal alpha-D-GalNAc and either terminal alpha-D-NeuAc or non-terminal beta-D-(GlcNAc)2 residues. Both the alpha- and beta-forms are sulphated on O-linked oligosaccharide side chains but are not phosphorylated. The hamster oviductin polymorphism is a consequence of different glycosylation patterns and not the polypeptide chain itself. Hamster oviductin is mostly O-glycosylated and contains a few N-linked oligosaccharide side chains (approx. 10 kDa). It is proposed that hamster oviductin is a mucin-type glycoprotein which might act as a protective secretion influencing the first steps of the reproductive process necessary for the normal triggering of fertilization and early embryonic development Mesocricetus auratus
