這個基因編碼連環蛋白家族的一個成員，這種蛋白在細胞粘附過程中起著重要作用，通過連接位于質膜上的鈣粘蛋白和細胞內的肌動蛋白絲。編碼的機制敏感蛋白包含三個長春新堿同源結構域，在細胞骨架張力作用下發生構象變化，導致鈣黏蛋白-肌動蛋白纖維連接的重構。這個基因的某些突變導致蝴蝶狀色素營養不良。[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]
