转录因子7 (TCF-7) (T细胞特异性转录因子1) (T细胞因子1) (TCF-1)

P36402

功能描述

转录激活因子,参与T细胞淋巴细胞分化。CD4(+) CD8(+)未成熟胸腺细胞存活所必需。缺乏N末端CTNNB1结合域的亚型无法发挥此作用。结合CD3E基因启动子中发现的T淋巴细胞特异性增强子元件(5'-WWCAAAG-3')。抑制α-β T细胞谱系中T细胞受体γ基因的表达(By similarity)。自然杀伤受体阳性淋巴组织诱导T细胞的发育所必需(By similarity)。TLE1、TLE2、TLE3和TLE4抑制由TCF7和CTNNB1介导的反式激活。也可能作为CTNNB1和TCF7L2靶基因的反馈转录抑制因子。 {ECO:0000250|UniProtKB:Q00417}。

组织特异性

Predominantly expressed in T-cells. Also detected in proliferating intestinal epithelial cells and in the basal epithelial cells of mammary gland epithelium.
