CTNNA1(catenin alpha 1),癌症关联基因,基因ID:1495,这个基因编码连环蛋白家族的一个成员,这种蛋白在细胞粘附过程中起着重要作用,通过连接位于质膜上的钙粘蛋白和细胞内的肌动蛋白丝。编码的机制敏感蛋白包含三个长春新碱同源结构域,在细胞骨架张力作用下发生构象变化,导致钙黏蛋白-肌动蛋白纤维连接的重构。这个基因的某些突变导致蝴蝶状色素营养不良。[由RefSeq提供,2016年5月]This gene encodes a member of the catenin family of proteins that play an important role in cell adhesion process by connecting cadherins located on the plasma membrane to the actin filaments inside the cell. The encoded mechanosensing protein contains three vinculin homology domains and undergoes conformational changes in response to cytoskeletal tension, resulting in the reconfiguration of cadherin-actin filament connections. Certain mutations in this gene cause butterfly-shaped pigment dystrophy. [provided by RefSeq, May 2016]。
