该基因编码一个属于免疫球蛋白（Ig）超家族的突触细胞粘附分子1（SynCAM）家族成员编码的蛋白在C末端附近有三个Ig样结构域和一个胞浆蛋白4.1结合位点属于蛋白质4.1家族的蛋白质与其他细胞骨架蛋白相互作用。已发现该基因编码不同亚型的多个转录变体。
This gene encodes a member of the synaptic cell adhesion molecule 1 (SynCAM) family which belongs to the immunoglobulin (Ig) superfamily. The encoded protein has three Ig-like domains and a cytosolic protein 4.1 binding site near the C-terminus. Proteins belonging to the protein 4.1 family crosslink spectrin and interact with other cytoskeletal proteins. Multiple transcript variants encoding different isoforms have been found for this gene.
