这个基因编码粘蛋白家族的一个成员粘蛋白是由许多上皮组织产生的高分子量糖蛋白这个基因编码的蛋白质被分泌出来，形成一个不溶性的粘液屏障，保护肠腔。[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]
