Abnormally increased signaling by the GTPase RAP1 favors progression of diverse tumors. We have characterized the auto-regulation and activation of C3G (RAPGEF1), an activator of RAP1. This led us to discover mutations in non-Hodgkin's lymphomas that activate C3G-RAP1 constitutively, suggesting that deregulation of C3G may favor the dissemination of tumor cells.
GTP酶RAP1的信号异常增强有利于多种肿瘤的进展。我们已经对RAP1的激活剂C3G（RAPGEF1）的自动调节和激活进行了表征。这使我们发现了非霍奇金淋巴瘤中激活C3G-RAP1的突变，提示C3G的失调可能有利于肿瘤细胞的扩散。
