It is composed of two subunits, alpha-ovomucin (MUC5B) and beta-ovomucin (MUC6), of which the beta subunit is much more heavily glycosylated.
This mucin is formed from two subunits, alpha-ovomucin (MUC5B) and beta-ovomucin (MUC6), with the latter being more heavily decorated with carbohydrate molecules.
