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 |

3.4.21.120 | proteolytic modification |
protease is translated as the N terminus of an unusual mosaic protein. It is proposed that during post-translational proteolytic processing of the mosaic oviductin glycoprotein, the processed N-terminal protease domain is released coupled to two C-terminal CUB domains and constitutes the enzymatically active protease molecule |

3.4.21.120 | proteolytic modification |
translational products stored in the pars recta granules need to be processed to become a proteolytically active 66000 Da form. Extensive posttranslational processing for activation of proteolytic activity. Oviductin translated as 107.6-kDa precursors are processed both N- and C-terminally to give rise to a 66-kDa active form comprising a serine protease and two CUB domains |
