LEF1（lymphoid enhancer binding factor 1），癌症关联基因，基因ID：51176，该基因编码一个转录因子，属于与高迁移率族蛋白-1同源的蛋白质家族由该基因编码的蛋白质可以与T细胞受体α增强子中的功能重要位点结合，从而赋予最大的增强子活性。该转录因子参与wnt信号通路，可能在毛细胞分化和毛囊形态发生中发挥作用。在体细胞皮脂腺肿瘤中发现了这种基因的突变这种基因也与其他癌症有关，包括雄激素非依赖性前列腺癌选择性剪接导致多个转录变体[由RefSeq提供，2009年10月]This gene encodes a transcription factor belonging to a family of proteins that share homology with the high mobility group protein-1. The protein encoded by this gene can bind to a functionally important site in the T-cell receptor-alpha enhancer， thereby conferring maximal enhancer activity. This transcription factor is involved in the Wnt signaling pathway， and it may function in hair cell differentiation and follicle morphogenesis. Mutations in this gene have been found in somatic sebaceous tumors. This gene has also been linked to other cancers， including androgen-independent prostate cancer. Alternative splicing results in multiple transcript variants. [provided by RefSeq， Oct 2009]。
