Tripartite motif-containing 24 (TRIM24), also known as transcriptional intermediary factor 1α (TIF1α), is the founding member of TIF1 family. Recent evidence indicates that aberrant expression of TRIM24, functions as an oncogene, is associated with poor prognosis across various cancer types. TRIM24 exhibits a multifaceted structure comprising an N-terminal TRIM region with a RING domain, B-box type 1 and type 2 domains, and a coiled-coil region, as well as a C-terminal plant-homeodomain (PHD)-bromodomain. The bromodomain serves as a 'reader' of epigenetic histone marks, regulating chromatin structure and gene expression by linking associated proteins to acetylated nucleosomal targets, thereby controlling transcription of genes. Notably, bromodomains have emerged as compelling targets for cancer therapeutic development. In addition, TRIM24 plays specialized roles as a signal transduction molecule, orchestrating various cellular signaling cascades in cancer cells. Herein, we review the recent advancements in understanding the functions of TRIM24, and demonstrate the research progress in utilizing TRIM24 as a target for cancer therapy.
含三联基序蛋白24(TRIM24),也被称为转录中介因子1α(TIF1α),是TIF1家族的首个成员。最近的证据表明,TRIM24作为一种癌基因异常表达,与多种癌症类型的不良预后相关。TRIM24呈现出多方面的结构,包括一个带有RING结构域、1型和2型B-box结构域以及一个卷曲螺旋区域的N端TRIM区域,还有一个C端植物同源结构域(PHD)-溴结构域。溴结构域作为表观遗传组蛋白标记的“读取器”,通过将相关蛋白质与乙酰化核小体靶点相连来调节染色质结构和基因表达,从而控制基因转录。值得注意的是,溴结构域已成为癌症治疗开发的极具吸引力的靶点。此外,TRIM24作为信号转导分子发挥特殊作用,协调癌细胞中的各种细胞信号级联反应。在此,我们综述了在理解TRIM24功能方面的最新进展,并展示了将TRIM24用作癌症治疗靶点的研究进展。
