OBSL1（obscurin like cytoskeletal adaptor 1），癌症关联基因，基因ID：23363，细胞骨架衔接蛋白在连接细胞内骨架和细胞膜方面发挥作用该基因编码一种细胞骨架衔接蛋白，它是Unc-89/暗蛋白家族的成员该蛋白包含多个N-和C-末端免疫球蛋白（Ig）样结构域和一个中心纤维连接蛋白3型结构域该基因突变导致3M综合征2型。另外，在该基因中发现了编码不同亚型的剪接转录变体。[由RefSeq提供，2010年3月]Cytoskeletal adaptor proteins function in linking the internal cytoskeleton of cells to the cell membrane. This gene encodes a cytoskeletal adaptor protein， which is a member of the Unc-89/obscurin family. The protein contains multiple N- and C-terminal immunoglobulin (Ig)-like domains and a central fibronectin type 3 domain. Mutations in this gene cause 3M syndrome type 2. Alternatively spliced transcript variants encoding different isoforms have been found in this gene. [provided by RefSeq， Mar 2010]。
