This peptide is derived from the tandem repeat of Muc 3 mucin protein. MUC3 is a membrane associated mucin of the small intestine. Probiotic microbes induce MUC3 mucin transcription and translation with extracellular secretion of the MUC3 mucins. Mucins are highly O-glycosylated proteins which polymerize through the formation of disulfide bonds to form a gel that is secreted onto the surface of glandular epithelia. Mucins play a protective role for the adjoining epithelial tissues under normal physiological conditions; whereas an altered expression of mucins is often associated with carcinomas and neoplastic lesions.
