上皮细胞极性的建立和维持失败有助于肿瘤的发生。细胞极性蛋白的表达和功能丧失与上皮细胞极性维持直接相关。极性蛋白光碟大同源物5 (DLG5)属于分子支架蛋白家族,称为膜相关鸟苷酸激酶(MAGUKs)。与其他家族成员一样,DLG5包含多个pdz、SH3和GUK结构域。DLG5以与DLG1和ZO1相同的方式进化,DLG1和ZO1是两种已经被充分研究过的MAGUKs蛋白。与DLG1和ZO1一样,DLG5在细胞迁移、细胞粘附、前体细胞分裂、细胞增殖、上皮细胞极性维持以及向膜和细胞骨架传递胞外信号等方面发挥作用。由于DLG5在炎症性肠病(IBD)和克罗恩病(CD)中的作用已被综述,在这里,我们的综述主要集中在DLG5在上皮细胞极性维持和癌症发展中的作用。
Failure in establishment and maintenance of epithelial cell polarity contributes to tumorigenesis. Loss of expression and function of cell polarity proteins is directly related to epithelial cell polarity maintenance. The polarity protein discs large homolog 5 (DLG5) belongs to a family of molecular scaffolding proteins called Membrane Associated Guanylate Kinases (MAGUKs). As the other family members, DLG5 contains the multi-PDZ, SH3 and GUK domains. DLG5 has evolved in the same manner as DLG1 and ZO1, two well-studied MAGUKs proteins. Just like DLG1 and ZO1, DLG5 plays a role in cell migration, cell adhesion, precursor cell division, cell proliferation, epithelial cell polarity maintenance, and transmission of extracellular signals to the membrane and cytoskeleton. Since the roles of DLG5 in inflammatory bowel disease (IBD) and Crohn's disease (CD) have been reviewed, here, our review focuses on the roles of DLG5 in epithelial cell polarity maintenance and cancer development.
