| Mucin is expressed by most glandular epithelia. Tandem repeats characterize the core mucin protein, apomucin -- variation of the protein derives from variation in the number of expressed repeats. Native forms of mucin are distinct in size and degree of glycosylation -- factors other than the primary structure of apomucin may contribute to these characteristics. Many complex O-linked oligosaccharides are presumably added by glycosyltransferases. Expression is increased in the lactating breast and in breast, ovary, lung, and prostate malignancies. It is a serum marker for breast cancer. Mucin Peptide MUC-1 is from the group Retired Concepts
