CDH18(cadherin 18),癌症关联基因,基因ID:1016,该基因编码一种ii型经典钙黏蛋白,来自介导钙依赖性细胞-细胞粘附的完整膜蛋白钙黏蛋白超家族。成熟的钙粘蛋白由一个大的n端胞外结构域、一个单一的跨膜结构域和一个小的高度保守的c端胞质结构域组成。II型(非典型)钙粘蛋白的定义是基于其缺乏一个特定于I型钙粘蛋白的HAV细胞粘附识别序列。这种特殊的钙粘蛋白在中枢神经系统中有特异性表达,可能参与突触粘附、轴突生长和引导。另外,已经发现该基因编码不同亚型的剪接转录变体。[由RefSeq提供,2014年5月]This gene encodes a type II classical cadherin from the cadherin superfamily of integral membrane proteins that mediate calcium-dependent cell-cell adhesion. Mature cadherin proteins are composed of a large N-terminal extracellular domain, a single membrane-spanning domain, and a small, highly conserved C-terminal cytoplasmic domain. Type II (atypical) cadherins are defined based on their lack of a HAV cell adhesion recognition sequence specific to type I cadherins. This particular cadherin is expressed specifically in the central nervous system and is putatively involved in synaptic adhesion, axon outgrowth and guidance.
