磷脂酰肌醇-3,4,5-三磷酸依赖性Rac交换因子1(PREX1)是一种编码基因,其在多种肿瘤中异常表达。PREX1基因编码蛋白作为一种小GTP结合蛋白Rac1的鸟嘌呤核苷酸交换因子(RacGEF)能够通过激活Rac1,形成PREX1/Rac通路,与多种经典信号通路发生串扰,参与调节肿瘤过程的多种受体反应,影响肿瘤微环境的上皮-间充质转化过程,在肿瘤的增殖、转移和预后方面发挥作用。

Phosphatidylinositol-3, 4, 5-triphosphate-dependent Rac exchange factor 1 (PREX1) is a coding gene that is abnormally expressed in a variety of tumors. As a guanine nucleotide exchange factor (RacGEF) of small GTP binding protein Rac1, PREX1 gene-encoded protein can form PREX1/Rac pathway through activating Rac1, crosstalk with a variety of classical signaling pathways, participate in the regulation of various receptor reactions in the tumor process, affect the epithelial-mesenchymal transformation process of the tumor microenvironment and play a role in tumor proliferation,metastasis and prognosis.
