CDH5（cadherin 5），癌症关联基因，基因ID：1003，这个基因编码钙粘蛋白超家族的经典钙粘蛋白。编码的前蛋白经蛋白质水解处理生成成熟糖蛋白。钙依赖性细胞粘附分子由五个细胞外钙黏蛋白重复序列、一个跨膜区和一个高度保守的胞质尾组成。作为一种典型的钙粘蛋白，通过赋予细胞以亲和力方式粘附的能力，这种蛋白在内皮-粘附连接的组装和维持中发挥作用。该基因位于16号染色体长臂上与乳腺癌和前列腺癌杂合子缺失相关的基因簇中。[由RefSeq提供，2015年11月]This gene encodes a classical cadherin of the cadherin superfamily. The encoded preproprotein is proteolytically processed to generate the mature glycoprotein. This calcium-dependent cell-cell adhesion molecule is comprised of five extracellular cadherin repeats， a transmembrane region and a highly conserved cytoplasmic tail. Functioning as a classical cadherin by imparting to cells the ability to adhere in a homophilic manner， this protein plays a role in endothelial adherens junction assembly and maintenance. This gene is located in a gene cluster in a region on the long arm of chromosome 16 that is involved in loss of heterozygosity events in breast and prostate cancer. [provided by RefSeq， Nov 2015]。
