Mucins are secreted as massive aggregates of proteins with molecular masses of roughly 1 to 10 million Da. Within these aggregates, monomers are linked to one another mostly by non- covalent interactions, although intermolecular disulfide bonds may also play a role in this process. Secretion [ edit] See more Mucins are a family of high molecular weight, heavily glycosylated proteins (glycoconjugates) produced by epithelial tissues in most animals. Mucins' key characteristic is their ability to form gels; therefore they are a … See more Human mucins include genes with the HUGO symbol MUC 1 through 22. Of these mucins, the following classes have been defined by … See more The functional classification does not correspond to an exact evolutionary relationship, which is still incomplete and ongoing. Known-related groups include: • The … See more Mucin genes encode mucin monomers that are synthesized as rod-shaped apomucin cores that are post-translationally modified by exceptionally abundant glycosylation.
