WebThe mucins are a family of large glycoproteins characterized by abundant O-glycans clustered in long mucin domains. These domains are extended stiff rods with the glycans pointing in all directions. This cluster of glycans makes the central protein core inaccessible to proteases and generates a glycan surface of clustered antigens. There are ...

WebAs shown in Figure 6A, ovarian cyst mucin O-glycans exhibited a high proportion of sialylated glycans (more than 50% of all the O-glycans identified). However, in contrast to intestinal mucin oligosaccharides, sialylated glycans from ovarian cysts were mainly based on a core 1 structure, with a small proportion of sialylated core 2 glycans.

WebO-linked glycans, in particular mucin, have been found to be important in developing normal intestinal microflora. Certain strains of intestinal bacteria bind specifically to mucin, allowing them to colonize the intestine.
