粘蛋白(mucin,MUC)是一类高分子量的糖蛋白,至今已发现15种[1]。它分为分泌型和膜结合型两大类。MUC1粘蛋白(以下简称MUC1)正常情况下主要表达于许多分泌性器官的细胞膜顶端,如唾液
Mucin (MUC) is a kind of high molecular weight glycoprotein. So far, 15 species have been found [1]. It is divided into two major types of secreted and membrane-bound. MUC1 mucin (hereinafter referred to as MUC1) is normally expressed mainly on the apical membrane of many secretory organs such as saliva
