這個基因編碼粘蛋白家族的一個成員粘蛋白是由許多上皮組織產生的高分子量糖蛋白這個基因編碼的蛋白質被分泌出來，形成一個不溶性的粘液屏障，保護腸腔。[由RefSeq提供，2016年12月]
This gene encodes a member of the mucin protein family. Mucins are high molecular weight glycoproteins produced by many epithelial tissues. The protein encoded by this gene is secreted and forms an insoluble mucous barrier that protects the gut lumen. [provided by RefSeq, Dec 2016]
