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. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2014]
